Maybe you have answered this before: you seem to be uncertain about your position for next year but you are acting as if you know you will be non-renewed ... Thus, have you asked your P directly, if he/she will be bringing you back for next year? At this point, what do you have to lose by asking for a direct commitment either way? Seeing how you are asking for LOR and have told your P you are applying elsewhere, why not just ask him/her if you will have a job at your school next year. Phrase it however you want, but I would ask because I would want and need to know. Districts are hiring now and it is only fair to you to get the truth.
