NEMA 14-30R (not 14-30P) to TT-30R?
My garage currently has a 14-30R (not 14-30P) 125/250V receptacle. Is it possible to rewire this to a TT-30R 125V receptacle? I can't seem to find an adapter anywhere.

If an overload on the one hooked up hot wire will trip the double pole, why do I need to replace it with a single pole? I'm guessing it's to "disconnect" the other capped hot wire?
So far as I know, you don't need to, at least from a safety standpoint. Code might for some rather obscure reason not permit it, or perhaps it just seems untidy to some people (as the dual-pole breaker implies a 240V or 120/240V circuit, not a 120V circuit).
Agree 100%, there is no need to change the breaker. Not all double pole breakers mean a 240v circuit, they are also used for a pair of 120v circuits with a shared neutral.
In fact you could add TWO TT outlets from this circuit, each capable of delivering a full 30 amps of 120v power. Since the hot legs are out of phase with each other, both can share a common neutral. Black to the gold screw on outlet #1, red to the gold screw on outlet #2, and white to the sliver screws on both outlets, and bare to the green screws on both outlets.
