No, it's just English literacy. You may spend a target lock to get a reroll or you may not. Once you commence a Proton Torpedo attack, the game instructs you to spend a target lock.

Yes. Which is exactly why you're wrong.
'You must do X in order to get Y' =/= 'You must do X'
This is basic logic. What you fail to understand is that you have no proof of any basis upon which you could spend a target lock for a voluntary purpose. The burden of proof is on you as you are advocating for something against the literal reading of the card.
