All of machine learning is AI. It's a subset, by definition.
It is true that all of this, machine learning, large language models, natural language processing and much more is AI, in the sense that it falls under the same artificial intelligence umbrella in computer science. It just feels a little like some one is using the term "construction" over and over, but what they are specifically talking about is some very specialized type of carpentry. It's not wrong, it's just not all that precise and give the wrong impression.
