I'd say Cheeseskates is right. Most of these FIGHTs are interactions. Only a small handful of monsters recognize Frisk as a human, so most of them are not attacking Frisk with the intention of killing them. You can look especially at monsters like Vulkin, who is trying to be encouraging and helpful, but doesn't realize that its attacks are harming Frisk.

One thing to note is how in the vast majority of FIGHTs you can flee immediately, and to my knowledge there is nothing that prevents Frisk from fleeing once the option is selected. Once again, there are only a handful of occasions when Frisk is not able to flee. If the monsters were actively attacking, they would certainly try to stop Frisk from escaping. In fact, generally when monsters are actively attacking you lack the option to flee (there are a couple exceptions).
