This metering at the xfmr. is odd. Usually you have to have a CT metering compartment in your switchgear.
You could offer to provide a termination compartment per USERC standards and pay the utility to install cables to that compartment, The termination compartment would be the designated point of service termination. The AHJ would only have jusidiction from there into the building.
Some utilities get nervous about having too many sets of large conductors terminated on the xfmr. spades. If the pad settles the secondary bushings leak because they are supported by the cables. Sometimes those utilities require a termination vault near the xfmr.
