HTTPoison tends to be a lot more featureful than HTTPotion as it’s based on hackney and HTTPotion is based on ibrowse.
If Hackney’s/HTTPoison’s pools are insufficient, have you looked at Tesla instead? It supports a variety of backends (the default recommended one is indeed still hackney) but a unified interface to them all so you can try different ones for your purpose.
You can’t. HTTPotion doesn’t support pools, so if you want to use pools you would have to use something like poolboy and join them together.

I believe Tesla is overkill. All I want to do are simple HTTP GET requests. Millions of them. Hackney can’t handle it so I can’t use anything that uses Hackney. But thanks for the link, it sure looks interesting.

This question was started because I was considering using pools with HTTPotion. The reason for this is that I usually default to using pools in every component I make without thinking, but Elixir is different in that processes are so cheap it is game changing.
