How did this 400amp service ever pass?

Sounds like you need to tap off the neutral and bond it to the enclosure. Separate the bonding of the neutral and equipment grounding conductor at the building

I believe W.Va is on 2017 code

Question for all. If this is an "emergency disconnect not service equipment" and seperate service feeder taps, can the seperate structures be bonded individually with own grounding systems? 2020 would seem to be so. If that is an allowable installation under the newest code would all that be needed is signage?

wouldn't that need to be utility owned and then?

The emergency disconnect rules only apply to one and two family dwelling units. It is unlikely that a 400 amp high leg delta is supplying a one or two family dwelling.

It was actually on B phase. Maybe original install was a WYE than had poco change transformer bank.

These banks used to be referred to as “red leg” deltas.
Goes on B phase at the breaker, C phase position at the Meterbase.

Utility slang.
The NEC went to orange, as the preferred new color, some +40 years ago.

Nope. Electrician slang... I said “used to be referred to”. How old was that service? It could have been from 1980 if that state didnt adopt the 75 until later..
electricians called this red leg for years after 75 when the NEC went to orange. Electricians that grew up in the trade in the 60s and 70s didn’t stop calling it red leg just because the NEC did.
I haven’t heard that in over 20 years, but it’s probably because most of the 70-90 YO electricians are done or dead…

Agreed on all counts, and it used to be 190v instead of 208v.
