And I am by no means a 6MT guru... If it was in gear then the countershaft was moving and lubricating the bearings and bushings in the transmission- the tranny might be ok.
Nothing happened to the diff that would not happen in normal service.
Typically, they'll put a manual RWD car in neutral, tow it, and that act will rotate the driveshaft and turn the output shaft of the tranny, but since the tranny depends on the countergear moving to splash oil up on the input, output, and synchros, and since in neutral the countershaft is not moving, the quickly toasts unlubricated bearings, bushings, and gears.
I would demand that the tranny be opened and inspected. The stress of turning the engine against its wishes could easily have broken a gear tooth lets say if the tow operator jerked the car a couple of times. I would not trust that tranny until I was absolutely sure of its health.
Clutch is probably smoked, but maybe not, all that stuff will be accessible though when they pull the engine. I would want each component of the clutch system inspected, pilot and release bearings, shift fork just in case it got jammed and bent somehow, slave, flywheel itself for glazing or heat cracking or other damage, flex plate.
The starter and ring gear are probably toast as well.
If it was towed in 1st gear then the engine will need to be broken down also. I'm not sure our engines can withstand 30,000RPMs (1st gear, 50mph) and I'm sure the valves are bent at the very least? Everything would have been moving pretty fast.

There is nothing on the internet about the radiator bursting due to towing in gear, being towed at all.
An experienced tow truck driver will be able to tell you more. But again... honestly, replacing the radiator is a minor, minor, MINOR, thing compared to other issues the car has going on. I would not even be worried about the radiator at this point. If the company is playing game with the engine and trans then start there... those are the multi-thousand dollar items...
I mean what... even an upgraded Koyo radiator for you car is $350. GReddy is $750. I believe the stock radiator is less than both of those... so don't get distracted by a $200 part when you have $4000 worth of damage in other places.

but i also want to protect my *** because he can easily say that there was prior damage to the engine and tranny because if i take the blame for the rad, he can easily say there was more stuff wrong with the car.... i came on this forum to find out if someone on this forum can have an explanation on how the rad burst... so far i liked all the responses but no one has hit the nail on the head yet

My theory is; car was towed in low gear, overreving the engine. Something breaks, if the engine had been running it would stop and that would be the end of it. However the engine in this case is being driven by external force. Continuing to spin with broken pieces and breaking more, trying to seize but it cant, developing tremendous amounts of heat violently boiling the coolant. Either that, or the alien spacecraft's heat ray. Best I can do man.

Take the G to the dealership.
Get it inspected.
If its a problem with the radiator then get it repaired.
If there are issues with the engine/transmission then get CAA to repair it through the dealership.
If they don't accept the cost of repair by the infiniti dealership then call an attorney.
The way i see it you're partially at fault. And if the CAA flat bed driver hadn't told you that the car was towed wrong then you wouldn't have known any better.
Basically if its a radiator problem then take the hit and make this a learning experience.
If its the engine / tranny then make CAA pay for it.

To all those who think the engine was running when the radiator burst at 50 miles an hour:
Wouldn't the car be making a loud sound if the engine is revving close to the red line?
How could the driver hear the cap pop over the sound of an engine that is close to red lining?
Either the drivers lying or the engine wasn't running.

^What are you trying you say again? 
I doubt the noise would be very loud since there's no combustion.

Now imagine that same scene with NO LUBE!
Remember fuel is NOT only a power source it is also a cooling source. the more fuel you add the less the temperatures will be. (hence why when you run lean the car gets hotter and tends to ping/knock.)
But you'd still have friction; and friction causes heat and metal to metal contact causes noise. Not intense, but noise none the less.
By the engine turning it will still cause the oil pump to rotate and the subsequently the water pump as well. UNFORTUNATELY if will NOT mean that the electronics are on therefore the fan's will NOT kick on.
This guy has MASSIVE engine and/or transmission failures due to the extent of that damage.

I can only hope my comical posts have enlighten you to actually take heed and call an attorney tomorrow morning.
Because the more the times passes by the less chances you have at winning the legal battle.
Ps, you can have the attorney go after their labor costs from them (them being the towing corporation)

If the pistons are moving fast enough for the radiator cap to pop I'm pretty sure they're moving fast enough to ignite any fuel in the cylinder causing a combustion.
