I think the author was close to something here but messed up the landing.

To me the difference between something like AI translation and an LLM is that the former is a useful feature and the latter is an annoyance. I want to be able to translate text across languages in my web browser. I don't want a chat bot for my web browser. I don't want a virtual secretary - and even if I did, I wouldn't want it limited to the confines of my web browser.

It's not about whether there is machine learning, LLMs, or any kind of "AI" involved. It's about whether the feature is actually useful. I'm sick of AI non-features getting shoved in my face, begging for my attention.
