It’s theoretically possible, sure, but the nice, pretty spiral arms that our Milky Way has indicates it probably hasn’t crashed into any other big galaxies recently. So we probably don’t have any rogue supermassives, just rogue normal ones which are much harder to detect.

That’s reassuring!
You would think we’d see the gravitational influence long before one comes near, however.
You mean with an unexplained orbit of Neptune? The reason we can’t find planet 9 may well be because it’s actually a black hole
