The text you quoted is not an example of the trope you highlighted. It genuinely comes across like you're calling it LLM generated purely because of the "em-dash", except it isn't even an em-dash.

And I genuinely admire the actual effort to get it right. You looked just enough to catch the error but not enough to prove it was human. Keep going, the tell is in there.

I genuinely have no idea what you're trying to claim. If you have a point, you should express it clearly. If you believe something to be the case, you should present evidence straightforwardly and make an explicit logical argument.
