Hiya f/f!
Happy new year to you everyone.
Okay, with genuine respect to the others, and speaking also from a straight chica perspective, i think TTD's approach is probably best. It sounds like you already have a kind of connection with her. Given that gentle tickling is a normal way friends interact especially across genders (in straight relationships) then his idea of going for the tickle can work.
But i would modify TTD's suggestion in just this way. If she trusts you, you don't want to do anything to jeopardize that by going and trying to tickle-torture her into answering a question that she really doesn't feel comfortable about. That is a sure fire way to undermine the trust. Since she doesn't know why you're doing it, it could very likely come across as abuse like you're forcing her against her will in a bad way -which you aren't trying to do.
I would suggest rather that you pick some minor thing that you can disagree over, say like what TV show to watch (assuming it's not her favourite) or wait for a moment when she tries to pull a fast one on you. That way when you tickle her the stakes are already questionable and there is no worry of breeching the trust.
Apart from that, i agree, go for it.

Happy tickling, f/f and good luck.
