If you can do opening torpedo attack and enemy is pure sub, yes your torpedo will hit the sub but deal no damage. Also, the closing torpedo attack will not target any sub.

CVL/CV with green planes only can only do opening air duel for air supremacy, and cannot attack ANYTHING at all. so that is pointless to tell others "CVL without red or blue planes cannot attack sub" because it cannot damage any ship at all.
