I know they take offense at DAESH but I have never heard that of ISIS but I'll take your word for it (they don't seem to need much provocation for offense).
Well, I'm just taking Wikipedia's word for it, so...
The spelling and pronounciation are not the same for the two in Arabic so I don't know that they make that distinction between ISIS the organization and Isis the Goddess.
Like I said, they don't call themselves ISIS. Wikipedia says they insist on being called the Islamic State, or rather
ad-Dawlah al-Islāmiyah. Of course, most actual Muslims refuse to call them that, because they are neither Islamic nor a state. As I said, they tend to be called
Daesh in the Islamic world.
And
here's a page giving the names used for Isis in other cultures. Historically, she was known in the Mideast by names such as Abd-isi, Amat-isi, Asdoulous, and Isidoulous. So probably the baseline form would be Isi. (The page says she was also called Ament, but that's a different Egyptian goddess, aka Amunet or Amonet -- a name familiar to
Stargate SG-1 fans, and also the name of Sofia Boutella's character (Amahnet) in the upcoming
The Mummy.)
By the way, the reason most institutions stopped using "ISIS" in favor of "ISIL" is because they were getting complaints from the dozens of organizations, businesses, etc. that were already called Isis beforehand:

However, maybe LoT could go with the more authentic pronounciation EE-sis and could help differentiate the English association between the two.
Well, that's the pronunciation of the Greek form of the name (although "ees-ees" would be more like it). According to
this site, the original pronunciation was probably something like Eset or Iset.
Well, apparently Neal McDonough has also signed on for another season of Legends, so if Damien Darhk is the big bad that would make sense.
That's odd, given that he's supposed to be dead. They got around that before by removing him from the timeline, but he was put back at the end along with the others. Well, maybe it'll have something to do with the temporal anomalies they created at the end of the season.
I also wonder if the Egyptian angle of Isis might bring back the Hawks for a guest appearance.
Ooh, I hadn't considered that. I'd certainly love to see Kendra again, though I have no interest in Carter's return.
