Yes, Shalom's death in the shoa is one of those viral mistakes that happen in online trees so often... Other than in my tree (on myheritage) you will not find a correct one (at least, I couldn't). It can be checked on Rhodes cemetery website or the testimonies in Yad Vashem or the Fondazione Centro di Documentazione Ebraica Contemporanea where there's even a recorded interview with her daughter where she explains this.
