Right, IRC R602.4:

Exterior walls don't actually require structural sheathing, or to my knowledge structural mid-height blocking. If you don't need wood structural panels for wall bracing to resist lateral loads, then you could sheath your exterior walls with foam sheathing or just a weather resistive barrier and siding.

So for an interior bearing wall that isn't part of the lateral force resisting system, I don't see any requirement in the IRC to sheath it.
