For what it's worth, it's not a state that Jamie particularly wanted to put Phil in - and when the man collapses, there's a genuine look of regret on his face. He drops the lid to one side, letting it fall wherever it wants to, and moves to the man's side, reaching down to yank the keys free from Phil's belt, holding them up to try and see what ones might do what. There's a lot of keys, though, and not a lot of time, so he thrusts the keys towards Lexa, knowing enough about glasses to know that since Cosima doesn't have hers at the moment she's likely going to have a harder time seeing where things need to go.

"Here, take these and see what you can do with them. I'll get the rest of his weapons."

Maybe Phil'll do them a favor and stay unconscious long enough for them to get out, and then maybe they won't have to kill him. But just in case he doesn't, Jamie means to be ready to do what he has to.
