They are the same thing. Some fansubbers used "Old Dei" as others used "Old Deus". Even so, in the Japanese dub, it is always pronounced as "Old Deus". However transliterating is by preference of the fansubber.

To answer your overall question of "Is this information based off of the Dubbed or Subtitled version?", information is always taken from the original source. So it would be off of the Japanese dub, or put simply, the English sub.
