If that "hit" was a fabrication, then there would have been no need to sacrifice Seal Team 6 in this operation.
The raid on the compound did happen. Osama Bin Laden, the CIA asset, was not there. He died in December 2001 as reported in the foreign press at the time. Seal Team 6 had to die to keep the official legend of Osama Bin Laden alive and to maintain the credibility of the War on Terror, on which the entire modern police state at home and all our foreign wars abroad are based.
Nope. Over time the Seal Team Six would begin to put the pieces of the puzzle together. And may or may not have publicialized their conclusions.
