1. I am pretty sure that there is a "comprehend languages" spell, and I will guess that there are feats that do something similar but I am not 3.5e expert so I can't point you to them.
2. Tiamat may have bestowed "comprehend languages" on the oracle.
3. There is a D&D 5e monk class feature that lets you understand all languages, but I am not sure if there is a 1 to 1 mapping of that to a similar 3.5e skill. Ya don't need omniscience, just a class feature.
Tongue of the Sun and Moon (5e)

Given that 3.5e is a bit more 'overpowered' than 5e, I'd guess a monk in that edition has something similar.
(I'll check the SRD in a bit)
He explicitly states how he does that. He's reading the translations. Occam's Razor. Or, for that matter, how do you explain him knowing Belkar's eventual fate and Roy and Elan's forthcoming family meetings ahead of time?
