Thst looks like a 3 phase 208Y/120 volt panel. Can you provide voltage readings?

What are the chances that happened here, IDK. My best guess with only as many single pole breakers as there and no pattern of skipping every third space - is likely a 208/120 supply. Two and three pole breakers are all located in bottom portion could make one suspect single phase arrangement in higher positions and three phase in lower positions but there also is a group of single poles and no skipping spaces at the bottom left so it is likely standard three phase bus arrangement and not a high leg supply.

If the over 150 volts to ground actually is an issue, likely not. AFAIK Class A type GFCI's are all listed for 120 volts to ground (nominal) max.
Would require a SPGFCI device for over 150 to ground. Which wouldn't be prohibited but also not required for this application. None of the 210.8 requirements go beyond a class A GFCI device and no application outside of class A GFCI capabilities is covered by 210.8. Keep in mind the appliances covered in (D) used to be in art 422, not all but what there was moved to 210.8(D) along with some more appliances in 2023.
