Making definitive claims about whether LLMs do or do not have specific properties absolutely does require precise definitions of those properties that can be used to evaluate those questions. Merely hand waving that LLMs didn't undergo the same evolutionary process is not a definitive argument.
For example, the Turing machines and the lambda calculus don't look anything alike, but they are fundamentally interconvertible, and so in a real sense they are fundamentally equivalent. Without a model, all of your arguments are completely unconvincing for exactly the same reasons, eg. that there may exist many paths to fundamentally equivalent ends.
