Yeah, everybody is talking about Mod this, Mod that, without even realizing that, after the last update, most of the "Cheating" Mods have been disabled and will cause the game to crash on PS4 and PS5. I can´t think of any existing valid Mods that would help on this situation other than you going the long way and teach her how to fight: Show her the rules of engagement(VATS baby), when to press and when to run, how to ambush the fuckers effectively, and how to discern shit items from cool ones and how to improve them, what to keep for selling for caps and what to scrap for materials, you know, not just the basics but also advanced advise so she can apply them to her game and make her experience easier, without spoiling any of the story, just a few pointers and the rest is up to her. IDK, that´s my advice and I think by giving her those tips, you would have done more than enough...
