It is unusual for bumblefoot to be on the side of the toe versus the bottom. Bumblefoot is typically caused by a combination of a poor diet and bad perches.
The lesion on the side of the toe was not caused by bad perches, but may be related to a poor diet. However, I feel that there are other factors causing this problem, too.
Surgery is one way to repair bumblefoot, but, although I have not had the advantage of examining your bird, this lesion from the picture does not look like it can be repaired surgically. I would be more inclined to think this is a dermatitis.
It is possible that a tissue sample could be taken during a surgical procedure to diagnose this. IF it is already spreading to different toes, something needs to be dome quickly to figure out what it is and what treatment is best.

Are there Avian Vet or two on the mainland, and can you get to the mainland with your bird? DO NOT ALLOW THIS DOG AND CAT VET TO DO ANYTHING ELSE WITH YOUR BIRD. They do not know how to diagnose and treat birds because they've not been trained in the art. They are also NOT licensed to perform any surgeries on birds, and you stand a real chance of losing your bird to improper anesthesia administration. Birds have no fat on their bodies, and their bones are hollow, so this means even a bit of an overdose of drugs can kill them. At the very least it can damange livers and kidneys which will kill bird in a while.
If you have any way to get to the mainland, please do so and start all over with them about your bird's situation. Also read all you can about bumblefoot while keeping an open mind until you can see an Avian Vet.3 weeks is too long to be on antibiotics, and your bird needs a break from them for a while. Too much of antibiotics for too long cause fungas yeast infections which then have to be dealt with. If you've seen no progress in 3 weeks, vet may be using wrong meds or have improperly diagnosed illness altogether.
