Of course ISA can serve as a short form of names like ISABEL or LUISA. However, it is also a historic name of its own right. It appears as ISI, ISA, ISO, HISO etc. or in composite (two stem) names like ISIBOLD, ISABERT, ISOHARD etc.
E.Förstemann (Altdeutsches Namenbuch, vol. I, München, Reprint of the second edition, 1966, col. 970) tries to explain it as Eis ("ice"), related to Eisen ("iron"). However H.Kaufmann (Altdeutsche Personennamen, Ergänzungsband, 1968, p. 217) contradicts this interpretation and states that the element ISA is but a contracted form of ISANA, iron. This goes along with Germanic naming patterns a lot better than "ice." There doesn't seem to be any etymological relation between "Eis" and "Eisen."
Besides, ISA is the Arabic form of JESUS.
I can't find anything about a goddess called ISA.
This is all I can contribute.
