It's more that "thinking" is a vague term that we don't even understand in humans, so for me it's pretty meaningless to claim LLMs think or don't think.
There's this very cliched comment to any AI HN headline which is this:
"LLM's don't REALLY have <vague human behavior we don't really understand>. I know this for sure because I know both how humans work and how gigabytes of LLM weights work."
or its cousin:
"LLMs CAN'T possibly do <vague human behavior we don't really understand> BECAUSE they generate text one character at a time UNLIKE humans who generate text one character a time by typing with their fleshy fingers"
