No, not really. You can put a net top on a rimless tank though. I know it takes away from the appearance a little but its better than finding dried up fish on the floor.
Any fish can be a jumper.
Ive seen the most unlikely specimens jump for no reason at all. A Tassel Filefish once jumped from a LFS tank. Wasnt spooked or anything.
One thought I've had, while I would still recommend a cover, what about Haliochoeres wrasses? While they may still jump for unknown reasons, my guess is if spooked they will dive down into the sand rather than out through the top.
Given the shape of these fish and swimming style I would still think they'd be a risk for jumping though!

My Six Line hasn't bailed in 4 years.
As for wrasses, most of them are pretty significant jumpers, and I wouldn't put one in a tank without a top, unless it's already dead; then it's unlikely to jump.
I've had those hit the top, too. If they're closer to the top they'll jump instead of going back down when spooked, and sometimes they hit the top for no reason I could see.
