“Or, the polarity changed in situ over thousands of years to reflect the polarity of the earth”
Polarity in rocks is based on the alignment of molecules before the rocks solidified. It is possible that a very powerful magnet could realign the ions, but I doubt the field from the magnetic poles would be powerful enough to do that.
If that did happen, though, then why wouldn’t ALL the blocks be realigned? Why would they find a couple of random blocks that were aligned differently?

Perhaps laboring under the standard theory that these structures were tombs distorts their actual purpose which could have been something to do with harmonics or generating power of some sort.
Whatever they were, they were machines of some kind (not the kind we know today (perhaps ‘device’ is a better word), and that purpose could have changed the magnetic structure. People do not build gigantic complex stone structures tuned harmonically to certain frequencies (as the structures on Giza are) as tombs.
