Does the DX Flagpole require a balanced or unbalanced ATU tuner?

A. This reveals a common misconception about balanced/unbalanced antenna systems. In a practical sense, all that balanced means is that a source of RF voltage/current is not connected anywhere to a ground reference. Said in a simpler way, to be balanced an RF source must "float."

It is true that most tuners today do not provide physically-balanced outputs. Some part of the network is grounded. Hence they are unbalanced tuners if used in a common way. But isolate them from ground as we do by not grounding the tuner and mounting it on an insulated mount, our tuner IS operating in balanced mode.
