1. Do you have a source for that "typo" idea? Don't think I've ever heard it. Why, then, would the pre-Christian Septuagint have eruthra thalassa (Red Sea)?

2. What is the Hebrew for "Red Sea," then? I b'lieve the same expression can refer to either.

There is some confusion. The Reed Sea is mentioned, and the Red Sea.

I heard it years ago; I don't have a source. It may be completely false. Mea culpa.

No idea. You would agree, though, that suf in Hebrew means "reeds" (cf. Ex. 2:3, 5), and not "red"?

Modern Israelis call the Red Sea yam suf, but that may be because generations of Bible translators have conflated the Sea of Reeds with the Red Sea. I know of no ancient sources which identified that body of water by name. (Just as there is no ancient Hebrew name for the Mediterranean; the modern Israeli name yam ha-tichon ("middle sea") is a literal translation of "Mediteranean."
