I normally don't use traps. But for the allos i really recommend you to use a trap.

Most animals i either stand on a high cliff of use a Griffin or a thyla/equus or similar animal to run after animals and tranq them.

But allos its not this easy πŸ˜‚. They are pretty fast, run all over the place. Back and forth. Left and right. Then back again to munch on you. Then run all over the place againπŸ˜΅πŸ˜‚. That makes the allos pretty hard to hit with out a trap.
