The fused disconnect ahead of the meters is what muddies the water. It becomes the service disconnect. The AHJ might consider the entire assembly to be the Service.
The ground rod would be at the fused disconnect, up to the point of attachment by the POCO. The Main Bonding Jumper would be in the fused disconnect.
The bonding of the grounded conductor (neutrals) in the meters are inheirent in the design of the meters. A problem the utility and the inspector have to resolve.
The disconnects on the load side of the meters would not have the grounded conductor bonded.
Better design would be to remove the fused disconnect. Or remove the fusing so it doesn't qualify as a service disconnect. Then the bonding could be done in each metered disconnect, with a connection to the ground rod (s) from each. Usually the utility does NOT want any accessable point ahead of their meters so removing the fusing and locking the disconnect could be the easiest way out of the problem.
