Proper code review takes as long as writing the damn thing in the first place and is infinitely more boring. And you still miss things that would have been obvious while writing.
In this special case, you'd have to reverse engineer the grammar from the parser, calculate first/follow sets and then see if the grammar even is what you intended it to be.
Author did review the (also generated) tests, which as long as they're comprehensive enough for his purposes, all pass and coverage is very high, means things work well enough. Attempting to manually edit that code is a whole other thing though.
That argument might work for certain kinds of applications (none I'd like to use, though), but for a programming language, nope.
I am using LLMs to speed up coding as well, but you have to be super vigilant, and do it in a very modular way.
