I feel like calling out enemy locations is pretty standard now for AI companions to do, but in this game particularity I would usually use L3 to mark enemy locations before I moved so I didn’t rely on her much for call outs, but I understand why its useful.
I only saw her do stealth take downs maybe a handful of times and a couple of those times it looked like the enemy AI should have noticed her. Which is why that doesn’t stick out to me.
I can understand why people would find some of her AI mannerism humanizing to her character, even though I don’t think they accomplish that in any new way, but I never felt like I was playing with another human during game play. It’s also possible that I had a unlucky run and just didn’t trigger these actions for her to preform as much as they could have been done.
