I am offering a product (via MCP) that interacts with LLMs and user data. Every single day I get user support emails to my inbox written by their LLMs with LLM hallucinations. If the user (a human) would have read them before, that would save me a lot of time and anger!

Your post sounds logical at the first glance, but has nothing to do with the reality. The topic title is totally on point! If the user would put human effort in it, I wouldn't get those crappy emails.
