OTL, The PLO and Libya received fair support from Uganda, and willingly provided pretty much the only competent forces on the Ugandan side for the war with Tanzania.
OTL, Kenya had fairly good relations with Israel (to the extent of providing logistical support for the Entebbe raid in 1976). Idi Amin had ordered the assassination of Bruce McKenzie, a Kenyan government official largely responsible for the support provided for the raid. In addition, a few years after the Uganda-Tanzania war, Kenya expelled several Libyan diplomats, and the basis that Libya was "a sponsor of state terrorism".
So, on balance, I reckon that the aid given by Libya and the PLO in OTL to Uganda will also be given ITTL.
