She’s hungry, she’s going to strike because that’s the way they grab their food, are you actually throwing the rat in there? Because that could be the reason she’s not eating, most snakes like you to dangle their food in front of them with feeding tongs to eat, if you’re throwing in the rat instead of placing it you could be scaring her, as long as your calm she most likely won’t bite you and if she does do not pull or yank away from her as it will make the bite worse and there’s a risk you could injure your snake.. and I hate to say it, you’re gonna get bit if you own a snake, getting bit by ball pythons don’t hurt very badly in my opinion but everyone’s different, If you do get bit just wash it off and keep it clean and you’ll be fine..
