Not directed to me, but, if it were one of our dogs or one my wife is training:
It would not eat out of a bowl again until you're done trying to correct this behavior. Take her meals along with some high value treats (freeze dried chicken liver is our go-to), and take the dog out to open uncrowded areas on leash with either a prong or e-collar, whichever works best for your dog being corrected (and please learn the proper fitting and use of a prong if you're going to. It should be very snug, borderline tight on the dog, and corrected using a single jerk straight up, so you need to be holding the leash/dog close to you). Stay far enough away from people that the dog isn't reacting, and feed/treat her over a 20-30 minutes walk in this area, i.e. dog sees a person from a distance, doesn't react - boom, jackpot of food. Do this for probably a week or two. Then the next week or two, get a little bit closer to people but still far enough away that she isn't reacting and repeat with praising with her food when she sees a person and doesn't react. Little by little you're getting closer and closer to people and showing the dog that good things come when people are around. The correction collar is there if needed, but ideally you want to gauge the dog's comfort level based on distance and don't get her to where you need to use it.
Eventually, hopefully the dog would accept a stranger tossing it a treat. But don't make her accept being pet or physically messed with by a stranger for a LONG time while this behavior is being modified and reinforced. Especially if it's an older dog. This could be genetic or the dog had a bad experience when it was younger (even if you didn't notice or it was before you had her), or a combination of both. So she may never be a dog that people can just run up to and pet, but you can at least get her to where she isn't reacting poorly because strangers are around. It just takes a lot of patience and incrementally bringing up her comfort level, which requires you to gauge and further her progress.
For example, we had a dog recently that was very dog aggressive. Fortunately still young and more easily modified. We used that same technique, except with dogs rather than people. After a couple months it got to where we could walk by a person on a bike path with their dog, and instead of reacting to the dog, she would look up to us for treats, ignoring the other dog.
