The balance between 'find edge cases' and 'hallucinate non-existing cases and waste your time' may be negative. LLMs are also not free, they cost significant money even today, when they are subsidized by marketing budget.
Even an hallucinated non-existing case (which isn't the norm in my experience) is still food for thought.
