The underground oceans might also be some kind of eutectic - say water and ammonia. It lowers the melting point to such an extent that it stays liquid at temperatures that would otherwise freeze water.

That's actually quite neat, didn't think of that possibility.

Who knows - but geophysicists can model these possibilities.

Just fyi with liquids it's commonly called an azeotrope, not a eutectic (which is for solids despite them being the same thing in two different phases).
Primarily different terms because it's different branches of engineering that deal with the two.
