Correct, you have no way as a typical BB to force him to become lit. Instead, you can sit your big chunky block of HP on a capture point, angling to his direction or using islands to limit torpedo lanes, and force him to either rush you or lose on points. It's obviously not the ideal endgame scenario, but the BB strengths of being orders of magnitude tankier than every other class and having the most threatening main battery in the game has to be compensated for somehow with significant drawbacks. The drawback is not being able to spot most cruisers and destroyers at will; if you could, then they would be the ones helpless in an endgame scenario with a BB, not you.
