I'd probably allow anyone in the stomach to attack with just about any weapon, although it would have disadvantage with anything not light. Even if they're using a maul, they could use it to punch the critter's kidneys. Spells, of course are not limited by being restrained, I don't think I'd apply the normal penalty for ranged spells.
Of course this is all pointless. Like the old joke about escaping the stomach of a whale, all you have to do is run around until you're all pooped out.
