Tokyo Dining has two menus, and that's what causes the confusion.
Anything on the regular menu is included in the
DDP. Some of these include a few pieces of sushi in a combo meal. There are no a la carte sushi choices, just what's included in the meal descriptions.
From the sushi menu only the combination sushi platter and the sushi deluxe platter can be ordered as entrees on the DDP. Small sushi orders are OOP.
