Does knocking out Lae'zel change anything?

In the Lae'zel vs. tieflings encounter, where we meet her for the first time outside the tutorial, she pushes us to choose a side. I don't really want to kill her, so would knocking her out keep her "alive", so to speak?

I knocked her out, and the tieflings just left. I can't wake her up again, so I'm wondering if this is one of the cases where the game treats "knocked out" the same as "dead", or if there will be a difference. From what I can find, knocking someone out is the same as killing them for all but a couple of (not noted) situations. Is this one of them, and I could see Lae'zal again? I don't want her to hurt the seemingly innocent tieflings, but she hasn't done anything bad enough to merit killing her. (But if the game treats it the same, I might as well, right? I bet she has some good loot.)
