I haven't seen this with any other EV maker's chargers but Tesla sells an adapter kit for it's 2nd Gen Chargers.
They have a 14-50 but there isn't a TT-30R however they have a 5-20 which can be mated to 5-30 with a passive adapter. Not ideal but better than nothing.

Proper way to use a TT-30R is to use a 14-30 or 6-30 and then adapt to the TT-30R. The Tesla adapters do not care what the voltage applied is. You can happily use a NEMA 14-50 adapter at 120V-50A, but it's kind of a stupid idea since power is so much lower.

Only the really, really big ones are 240V split-phase with a NEMA 14-50R receptacle. It's a 4-pin connector, with an additional neutral blade, but it's not a twist-lock:

It's not likely to break anything or hurt anyone if you know what you're doing, but with the ridiculous number of variations and non-standard wiring you'll find out there, be sure you do know what you're doing!
