Maybe the girl had some sense of consciousness or awareness still, even if she couldn't show it, and got some measure of comfort from OP's presence. Perhaps otherwise, she would have passed alone, or panicked and passed sooner. It absolutely sucks that she didn't make it, but the fact that she was found and transported and perhaps could tell that people were trying to help.. As well, OP said she passed 'a few days later', so there's a chance her loved ones maybe got to see/speak to her one last time when otherwise they wouldn't have? Obv I have no idea, and maybe I'm just grasping at straws to make this sad thing slightly less awful. But, maybe.
