There is rather more to type than the em dash, kicking off with the difference between say a typeface and a font (or fount). Why not get into leading and kerning and the other stuff? Widows and orphans anyone? Getting your knickers in a twist over a minor typographical construction is rather contrived as an indicator of a non human author of a text. It will do for now but won't tomorrow. I can mostly spot LLM output on sight but I can be fooled. I never use silly rules like "em-dash => LLM". That's just silly.
