How does human will fit with Pratītyasamutpāda?
You have asked a very good question, I remembered if correctly it's in the Sutra of Perfect Enlightenment Maitreya Bodhisattva asked similar question: 以幻修幻 - how can if phenomenal world is illusory construct and the "I" is also illusory that a practitioner realize the Ultimate Truth? I remember the Buddha answered 以幻修真 - using the illusory to rid the illusion, as if using a wedge to get out another wedge stuck in the hole. Therefore, I think to give some help of your inquiry is to think of: your volition is to get over ignorance by choosing actions of not ignorant... You find that the action that is not ignorant is still an ignorant action... so on and so forth. Until you finally know the action that is not ignorant, that you are enlightened. It could be a long practice, or it could be a sudden realization. A bit like someone doing a difficult math equation, volition discerns the answers are not correct, over and over, that the working out incorrect answers are the footings to finally have the correct answer. Volition the ability to discern doesn't get hindered by ignorance, although ignorance prevented it from knowing the correct answer immediately. The Sutra has very good analogy full of wisdom far better than I presented here, I just recalled to make an answer in convenience. I hope I didn't misunderstand your question, and I'm not quite familiar with the terms and the Suttas mentioned in the OP.
