In those cases where there is no neutral splice or connection inside the CT enclosure (insulated neutral passes through the CT can without termination or splice), as is fairly common for remote CT enclosures, we would not require a splice, tap or termination of the grounded conductor within the CT can. I suppose technically it is bonded to the grounded conductor by way of the bonding conductor at the service disconnect, but we don't require service side main bonding jumpers. No different than when service conductors pass through pull boxes in a conduit run before entering the service disconnect enclosure. Bonding of metallic conduit and bonding bushings, but no bonding jumper to the grounded conductor. But like I said, I think it's an AHJ call whether to require it or not.
