Does she have dark skin? It's entirely possible that she has some surface bruising or skin irritation if the matting was bad enough, both because the mats themselves will constantly be pulling at the skin and because getting a clipper between mat and skin can be difficult in bad cases. You can't always feel this on the surface of the skin, and it won't be very visibly obvious on darker-skinned dogs, might be more so if she has lighter skin.
It's a huge change for her either way, and it's likely that the groom itself was very stressful because it had to be so extreme and she'd never experienced anything like it before. You can absolutely try a shirt or sweater on her to see if she acts more herself with that, but most likely she just needs time, even though it feels like she should've had enough already. Try to keep her routine normal and engage her in fun activities and training to help take her focus on it.
It may be worth videoing some of her scratching behaviors, just in case they persist, so you can show the videos to her vet. It can be hard for vets to figure out an issue if they can't see the behavior the owner is worried about, and a clear video or two is the next best thing to them seeing it happen in person.
