It's not that much of a stretch: give the LLM a top-level proposition for the thing you want to prove and have it hack away at it. Each sub-step is verified in lean so you know it's correct. But, the linked post definitely suggests otherwise.
That is definitely interesting because how do you know the 88 hours of work are correct before you throw another 17 hours of lean formalization work on it? You could end up just finding out there was some hallucination in the original work.
