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

Imagine stretching an elastic band or a spring until it breaks.
Now imagine stretching a chain of two until they break – you have to pull further, but you have to pull just as hard.
A very long drill isn’t any weaker, so it’s no more likely to yield or break than a short one, it will just bend/stretch further than a short one – as long as the rotation force gets to the cutting bit at the bottom, it’s doing its job.
