Octopus in the right circumstances could literally break your arm with the force they generate. And tentacles could easily swing an axe. And they could easily twist bolts, in fact there are videos of them doing that type of thing on youtube. And there are tons of land mammals that have prehensile limbs, like elephants, monkeys, etc. I’m not sure what information you’re using to mentally model what tentacles can do, but it’s quite inaccurate
I have no objections to aliens with prehensile limbs. Often wondered why humans are lacking. Must not have been so useful or we would have something more than a tailbone. But maybe another planet, another species, would have found limbs like that a bonus. Not ruling that out!
