The EOs receive last rites too.
Pope Leo XIII, Satis Cognitum (# 9), June 29, 1896: “So, with every reason for doubting removed, can it be lawful for anyone to reject any of those truths without thereby sending himself headlong into open heresy? without thereby separating himself from the Church and in one sweeping act repudiating the entirety of Christian doctrine?... he who dissents in even one point from divinely received truths has most truly cast off the faith completely, since he refuses to revere God as the supreme truth and proper motive of faith.”
Yes, but EOs have been formally declared schismatics and heretics by the Church. Trad groups would at worst be undeclared heretics, and at that, only condemned by other trad groups, such as MHFM.
We don't have any knowledge of her eternal state here. She died as she lived.
