I’m going to look into options of me pulling it and getting to a machine shop then ordering larger pistons or see what a local shop that is reputable might charge? Any advice is appreciated!!

This is still the same shop that said 4 cylinders not close to each other are all bad? Hmm... Maybe someone else knows differently but I've never heard of passing a leakdown but failing compression test. The compression has to be leaking from somewhere. Maybe if you broke a rod? But all 4? Nah. Also, a leakdown is significantly more involved than a compression test, so if both are going to be performed everyone I've ever known does the compression test first to see if a leakdown is even worth doing. Smells fishy. Don't worry about buying any parts until you find out what it needs. Get a second opinion before anything if you're not confident doing the test yourself.
