You are still stuck in thinking consciousness is one unified thing, but it is about one of the clearest examples of a family-resemblance category as you can think of.

Dynamicness / change is one aspect that is definitely part of what we tend to think of as being quite fundamental to consciousness, and there are a lot of ways in which LLMs can't and/or don't really change, and this strongly constrains how similar LLM consciousness can/could be to ours.

If the SEP isn't enough to trigger the thinking needed for you, just ask an LLM what I said, to "go through the ways in which LLMs do/don't/may exhibit phenomena that are generally what we consider fundamental aspects of consciousness". You'll see there are some clear answers, and some uncertainties and vagueness.
