Literally always LLM. AI is now synonym for LLM, regardless of what it meant before. Just like crypto is now synonym for e-currency and does not mean cryptography anymore.
I've worked at a company whose product involved some decently advanced computer vision, marketed as AI (which isn't incorrect).
I've also seen companies that were doing machine learning before the LLM boom, who remarketed their machine-learning-based product as AI (which isn't incorrect).
People are not confused about these.
