Can a tornado exist without the cloud touching down? Can it essentially be invisible and still destructive?

Technically all tornadoes are invisible. It is just the wind picking up dirt, objects, rain, etc. causing you to see the way the wind is moving. Tornadoes happen sometimes without being seen. They can be created in labs with no dirt and be invisible.

As for being destructive that is possible but you would likely see stuff still being moved.
