LLM will not be able to raise alarm bells
this is like the "benefit" of what LLM-therapy would provide if it worked. The reality is that, it doesn't but it serves as a proof of concept that there is a need for anonymous therapy. Therapy in the USA is only for people with socially acceptable illnesses. People rightfully live in fear of getting labeled as untreatable, a danger to self and others, and then at best dropped from therapy and at worst institutionalized.
I was an addict in my 20s and I was such a bad partner it cost me my engagement. Playing MMOs was my highest priority, friends and lovers were an annoyance. I couldn't grow up until years later when having personal realization about how I was projecting my desire to learn and achieve things in real life onto a game where achievement and progress is spoon-fed to you and requires no risk or effort from the player. Anyway, I think if a person is demonstrating with their actions that video games are more important to them than you are; you should listen. As painful as that may be in the short term.
