Yes, Ka and Kb are only assigned to weak acids and bases because Ka and Kb are the equilibrium constants for the dissociation of acid or base in the water and if you have a value for Ka and Kb that means that the acid or base isn't fully dissociated yet and not being completely dissociated is related to weak acids and bases as strong acids and bases completely dissociate.

What, hypothetically, would be a situation that we use strong acids'/bases' Ka and/or Kb?

I agree. The larger of the value of these constant would indicate strong acids/bases.
