Since they had no naval air arm left worth considering, it makes less difference than one might think.
Leyte Gulf ends with Yamato and the BBs sunk, as there is no credible decoy force to lure Halsey north. So a few US DEs and CVEs don't take a pounding from Kurita's BBs, but others do face the first Kamikazes.
Either way, at Leyte and in subsequent weeks as H.P. Wilmott discussed in his recent book on LG, the IJN is emasculated and ceases to be a consideration. The Kamikazes become the only thing slowing the advance of the US Pacific Fleet.
WW2 still ends as OTL, in mid-August, after Manchuria and the bombs.
