I'm glad your pit will recover. You have beautiful dogs. I don't think you have to re-home your GS dog but don't put your pit in harms way anymore now that you know there is a problem just deal with it. I don't make it a issue with my dogs and the behavior is toatally manageable.
Shock Collars can be great for some dogs but are not good for aggressive behavior as the dog may think it's the other dog bitting them in the heat of the moment and it could make things worse. They are great for off line training and walks in the country - once the dog is properly trained with its warning beep you won't need to zap them with the shock collar and you can go anywhere off line.
I have my front yard fenced for our dogs with electric fence (fed from our horse pasture). We live in the country and eveyone enters the house through garage anyways. The fence is 3 strands of wire at 4", 10", 16" and at 24" I have 1 1/2" tape fence so people can see it. We have a side fenced section the same way so I can keep dogs apart when outside and unsupervised. I can disconnect elec and move step-in post to mow the fenced yard. The fence is low enough to make people realize IF my rotts wanted out - it wouldn't be a problem! LOL It's also low enough we can step over it and the low wires keep out rabbits, skunks etc. from wandering near house. However - this past winter the snow got deep and hard enough that rotts could walk on top of it and their fence was then only inches high and they still stayed in their yard. : ) They love being outside and they all have a dog house if they need it.
I have 3 rotts a 7 yo male,3 yo grump, and coming 1 yo female (I bought back after selling - because she didn't have a good home) we also have a 16 yo female JRT. I spayed the young Rottie before she had her first heat and do not let my 3 yo grump with JRT at all - as problems started when my rott grump got to be breeding age. I can call her off the attack but no one else could or can. Shes not really dog aggressive but, it's natural for her to not want any other intack females in her house and its in her DNA as a German bred rott.
All my dogs are good with other dogs and well trained - I have even been told I should be showing all of them. I understand at home my grump gets territorial and she is the queen over our other dogs and they will submit to her or else so, we don't put her in a situation where she would get in trouble for fighting or worse killing our JRT.
IMHO underground fence is fine but if the dog chases a rabbit or goes through fence and gets zapped it won't want to come back in. A solid fence - electric, chain or other type is better.
