AI physics isn't worth worrying about compared to other inaccurate things kids see in movies. It doesn't seem to hurt them.
If you really want something to worry about, consider that movies regularly show pint-sized women successfully drop kicking men significantly bigger than themselves in ways that look highly plausible but aren't. It's not AI but it violates basic laws of biology and physics anyway. Teaching girls they can physically fight off several men at once when they aren't strong enough to do that seems like it could have pretty dangerous consequences, but in practice it doesn't seem to cause problems. People realize pretty quick that movie physics isn't real.
