If she isn’t feeling well, she may be starting to associate the litter box with her discomfort. I would definitely ask your vet about the diarrhea to see if there is anything you can give her in the short term to help her bowels until she has had time to adjust to her diet. This may be a probiotic such as forti-flora, or often times giving a little kayopectate can help a lot, but again with such a little kitten that has recently been through so much, I think consulting your vet would be best.
