Don't think aerial refueling fits the original posters intent:

"which post-WW2 combat aircraft (any country) have NOT been used in their
intended roles in an actual shooting war (or police action, or soccer riot,
or whatever it's called these days)?"

I don't think a B-50 ever dropped a bomb in anger.

An F11F did shoot itself down accidentally by diving through the path of its
own shells, but I don't think that counts as a shooting war.
