Based on the experience of 20 years ago, though, users are _extremely_ turned off by it. There's little reason to think this has changed (if anything it is likely more pronounced because Clippy came in kinda without baggage, whereas LLMs have a lot of baggage and most of it ain't great).

I really don't think it is. Clippy was reputationaly damaging to Microsoft and they had to get rid of it. There's little reason to think this will be different.
