I think its because animals are many interconnected systems or models which are made to create "intelligent" behavior, like one for speak one for movement and alike. LLMs are trained purely off text, so they are more similar to a very simple animal that only has one type of inputs and outputs like a worm that only knows where its body is and then where it wants to be. LLMs are also only trained for a short period of time, and thats when something interesting is going on and its able to learn and change. We then take a snapshot of it and give it different inputs to get some result instead of to teach it something. I would say that a crow brain that has been frozen and can only get a certain amount of inputs and then only produce a certain amount of outputs is not intelligent.
