This is, trivially, not intelligent nor conscious:

  function add(x): return x + 1; end.

An LLM has a bit of randomness to its calculations but that does not change the fact that

  function add_random(x): return x + rand(1, 10); end

is also just math. No personality. There's nobody home. After the function ends there is no residue.

An LLM does a lot of calculations but that doesn't change how it works.
