I don't know what too "vetty" is but you have an extremely sick pup who is suffering and needs veterinary care ASAP. I don't mean to come off harsh, but all this stuff about money and a nutritionist and all is way too much for my head. Layla needs a board certified specialist YESTERDAY. I am so sure her seizures were related to a liver shunt.
I hate stories like this.
Breaks my heart.
As Taylor said, she needs proper care now OR please, please consider surrendering her to a rescue that can help her. Her quality of life is bad now and will be worse if you continue this crazy diet you are feeding her. Medical management and diet "might' help BUT her life WILL be shortened.
As to how high....I can tell you her numbers are CRAZY HIGH and she is very sick and needs treatment NOW. Has your vet suggested lactulose? Any meds??
I will be back later to add to this but can't stay right now. I am going to post a link here for you to read in the meantime:

In the meantime, also look into Care Credit to see if you can get approved to get the right care for LaylaH
