I read Blindsight long before modern LLM AI came about and at the time I thought the aliens being intelligent without being conscious was fascinating and gave me a different perspective that those things could be separated but it didn't have and direct application.
Learning how modern AI's respond immediately made me think about how Rorschach was communicating with the crew and how current LLM AI's might be considered intelligent while not conscious.

How do you even know that LLMs are not conscious?
I've just skimmed the Wikipedia entry you linked:
So it turns out I'm not conscious either and incapable of semantic understanding, because I've ignored the ambiguities too. Though note that parsing ambiguous sentences used to be exactly what pre-LLM AIs could not do, and what we thought of as requiring real understanding. The exact opposite of what Watts seems to claim.
