Someone told me that there is a rule that the owner of the game has supreme ruling power when a dispute arises, but I haven't found such a rule anywhere. Is it official?

From the Conflicts Between Cards and Rules box of the Rules:

Of course, this is only if there is a deadlock, and the official rulings provided here by Andrew Hackard and MunchkinMan overrule anything else.

Some cards state that you must draw cards from either deck (like Duck of Many Things). English is not my primary language so I have difficulty figuring out if that means fx. one Door and one Treasure or one Door or one Treasure?

It means you choose only one of the decks.
