I don't know that I'd worry about food yet. It hasn't been long since the attack, and she might still be in a little bit of shock. If she's drinking, I'd wait. You can maybe put some NutriDrench in her water. Syringe feeding isn't super difficult, but you'd have to force her to take it, which...
My thoughts, too, esp after seeing some other raccoon attacks. Keep those wounds clean, as others have said, and I'm sure she'll be fine.
So sorry this happened! 😢
