The subfloor dips about an inch on one axis across the middle of the room. Structurally, I think this is due to old and rectified foundation issues. Since the dip is just 1-dimensional, can I install the flooring so the T&G bend with it? Or should I pull the entire subfloor up and level it at the joists?

I certainly would not lay the flooring down over an unprepared floor. I have done this and the flooring ended up splitting, cracking and making noise. I would reinforce the flooring and make it level with floor filler prior to laying the new flooring.
