Transitioning to Formula with a Super Sensitive Baby

My EBF baby is 5 months and i have had to be dairy, soy, gluten and egg free to manage her tummy issues and eczema. If i have dairy she gets super gassy, fussy, and tons of mucus in her poop but no blood so am told its not CMPA. She always has liquid poo and the pediatrician said it is normal.

I am trying to combo feed because I cannot keep my supply up, care for her, and succeed at my job. Something has to give. I tried Kendamil Goat and A2 Platinum and both were terrible. Kendamil Goat was slightly less terrible but she was still gassy, pooping 6+ times a day and spit up a lot on it and it smells revolting. On the A2 Platinum she was super gassy and went from having loose stool to explosive diarrhea, super fussy, and tons of silent reflux Poor baby!

I was given a can of enfamil gentlease to try but hate the ingredients. Was looking at Bobbi Gentle as well. I want to try a hydrolyzed protein formula thats soy free. I feel like most people have babies who get constipated on formula and I have the opposite issue.
