Good question but very unlikely. Specific battle plans were not disclosed. It was more about weapons deliveries and troop and battalion strengths.
In addition, the leaked documents had been modified. American estimates of Ukrainian losses were overstated in the leak and American estimates of Russian losses were understated. This doesn't rule out the leak being a ruse but the lack of specific battle plans probably does.
BTW: I enjoyed the the 1956 film
the Man who Never Was (with the wonderful Gloria Grahame) about another WW2 deception called Operation Mincemeat.
