If you ask an LLM to do a statically verifiable task without writing a simple verifier for it, and it hallucinates, that mistake is on you because it's a very quick step to guarantee something like this succeeds.
I mean, step 0 is verifying that the code with changed names actually compiles. But step 1, which is way more difficult, is ensuring that replacing v01 with out_file_idx or whatever, actually gives a more accurate description of the purpose of v01. Otherwise, what's the point of generating names if they have a 10% chance of misleading more than clarifying.
