Despite the clutter you can see her stuff enough. Her audio clue is soft on purpose, it's a trap. Do the fight enough times and you should get a feel for what lines aren't her instant kill and what the animation build up to it is. There's actually a few seconds you have time to get away but you do have to be paying attention to when she moves and when there's a pause and which red circle around her it is. It's a git gud moment and for the most part you can still be rezed if you derp.
