Only one pin really needs to be removed, at least for now. The ball mount can stay at the same drop setting.

have them undo the 4 bolts with air socket tool
have the locks cut or blow torched
put receiver back on and tighten 4 bolts with air socket tool
That's an interesting approach, and has potential if there's no other way to get safe access to the pin holding the ball mount in the receiver. On the other hand, it's a pickup truck so there should be more than four bolts; eight or more would be typical for Toyota - I don't know about a Ram. The receiver is also likely to be integrated with the bumper structure, so it might not be a trivial exercise.
With any luck nothing more than perhaps removing the spare will be needed for access.
Maybe it's just me, but I would certainly prefer to keep a torch away from any part of the vehicle or hitch. Sawing (or cutting with an abrasive disk) is more appealing, but of course locks should be designed to make this difficult.
