I think you have an excellent point here

in consequence of the missive, Darcy's determination, penned by Line
Line, concerning the limits of the theory of the Omniscient Narrator permanently standing in Elizabeth's shoes. With Austen, it is never a rigid posture. We come and go as she choses to visit other characters' streams of consciousness - although Elizabeth is her home base.
Yet concerning this partidular point of Darcy being "determined to be pleased", it also is, IMO, a tongue-in-cheek commentary, an admirable example of dry humour, showing that the ON is not to be taken in : his attitude is not only caused by love, but also shows a trait of Darcy's character:the strength his willpower concerning his opinion towards other people. He is not the spontaneous kind!
