Yeah.. Normies for sure don't use the term "LLM". I don't think it would scare them though. They're used to being confused 💀
When I see "AI" I think "tech bro hype" whereas "LLM" makes me think the developer is more likely to have a realistic view of the technology.
I guess this depends a lot on your target demo. But but even just cutting down on usage of the exact term "AI" would help I think. Basically anything is better.
