If we're spitballing, one could simply angle the impacts of asteroids to add momentum in the desired direction.

With that much atmosphere that’s a lot of tidal forces too, if you just get some I to orbit.

But the question. Is do you spin it backward or slow it down to spin it the right way, creating a situation where one side of the planet always faces the sun for a while. Might be an opportunity to freeze and cart off the other side of the atmosphere…
