We don't know if they all died. Maybe a few survived and she already sent them away, while she waited for the last two members (Doriarte and Minerva) to return.

Though I wonder why the building was wreaked. Wouldn't the Succubus Eye members be delighted to get the chance to join Tartarus?

Or did some of them start to fight back once the first few were turned into black shikigami?
