How deep drilling(oil, etc) avoids drill twisting on its axis? Wouldn’t kilometers long steel drills be akin to licorice?

The pipe is quite strong in that axis. There will still be some amount of twisting but no permanent deforming. It just means that you need to spin the pipe a few times before the head starts spinning at the bottom of the well. The pipe is selected to be strong enough to withstand these forces.
