The US hasn't supplied Ukraine with aircraft capable of flying SEAD/DEAD according to USAF or NATO doctrine. The Fulcrums launching HARM (old versions at that) are using 10-20% of the missiles capability. So no, other than one old missile, they're not using US gear, nor US tactics, nor US ISR for SEAD/DEAD.
