Leave her alone and let her come to you. I've rescued rabbits that had been abused/neglected like that and the best thing to do is to go about your daily business and ignore the rabbit. You can offer her treats if she'll take them but don't grab her (although I understand you need to handle her for grooming). Once she's comfortable enough to take treats and sit near you, try gentle petting.
Keep in mind, however, that a lot of rabbits just aren't cuddly. You lucked out breed-wise, though, most of the angora rabbits I've handled were docile and snuggly
. So she might just need time. Do you have plans to get her spayed?
One of the rabbits I rescued was TERRIFIED of people when I got her (much, much worse than your angora). I let her free-range and never picked her up (except for vet care) or anything--I would just ignore her. After a few weeks, she stopped running away immediately and I got her to take some treats. After a few weeks of treat-giving, she let me pet her and after that was a total snugglebun
. She never liked being picked up (most rabbits don't) but she enjoyed being pet and also learned some tricks (and games, like rolling a ball to you, haha).
By the way, thank you for rescuing her! It sounds like she had a rough time
