You’re correct as to the negative connotations of “jackass,”, but it should be noted that TV Trope names are just that and don’t necessarily apply to every trope that fits them. A genie might be intentionally twisting a person’s words to make the outcomes bad for them, but for good reason - they still fall under that trope. Perhaps it needs a name change.
I guess I should defer to a native speaker but I personally don’t think the word fits, in the same way I wouldn’t call a sick person lazy.
But on second thought, an American absolutely would call a sick person lazy.
Especially the current majority of their democracy.
