I would absolutely stop eating a meal if I learned AI was involved in creating it. I suppose I wouldn't literally spit it out but I wouldn't take another bite.
First, I would find it disrespectful. But second, I would be concerned that the LLM would tell the human to do something dangerous (like undercooking chicken) and since the human is apparently so desperate and clueless that they're using an LLM they wouldn't know it was a problem.
