It's impossible to say why the initial altercation occurred without having seen the events leading up to it, but factors that could have contributed would be: territorial behavior on both/either her and/or the Bostons' part- they entered her yard, and they clearly thought they had some stake in said yard to come cruising on over. She was tied, so confined, which can make a dog feel more defensive and quicker to display aggressive behavior. Multiple bull breeds- Bostons are simply bred down bull and terriers, and some still maintain the desire to respond to a challenge from another dog, or even start a scuffle; and as a pit mix, she might be inclined to be less tolerant of other animals, particularly if they challenge her. Is your Mom's dog a male or female? Same sex dogs are generally more apt to have conflict than opposite sex, but if the male Boston sees his housemate in a tussle, he's likely to join in. Your girl is also just reaching maturity, and at an age where many dogs (particularly bull breeds) become less tolerant of other dogs' shenanigans, so where she may have tolerated your Mom's dog 6 months or a year ago with just occasional "bickering", she might feel differently now about the same dog, and certainly less amenable to a pair of strange dogs intruding on her turf.
Unfortunately, it sounds like she and your neighbors' dogs now have something of a grudge match going, and IME it is not very likely that they will recover to the point of being "friends". My suggestion would be to invest in a better collar and tie out, as what your are currently using is not sufficient- she cannot be allowed to escape and fight with neighboring dogs. However, knowing that your neighbor's dogs will attempt to come into your yard after her, it is not safe to leave her unattended tied even in your yard. You have all been lucky that no dogs have been injured thus far, but given the opportunity, they will continue to fight and one or more will be injured or worse. Given the size gradient between a pit/lab mix and small Boston terrier, it is very unlikely that your dog will be on the losing end, which means she could be declared dangerous by your local animal services or you could be responsible/liable for vet bills.
The only safe way to continue to tie her out unsupervised would be to build a perimeter fence to keep the neighbor's dogs out of your yard. Alternatively, you should be going out with her when she is out, whether on her tie out or on leash; and ready to run interference if the neighbor dogs try to pay a visit.
You might be able to improve relations between the dogs through training and slow, controlled introductions, but should enlist the help of a trainer to help develop a plan, as failure could result in injury to dogs or people if a fight breaks out.
