Languages don't have to be relevant. The simplest way to resolve any apparent conflict here is to use the old "It understands X languages but never actually speaks" phrasing. I think dante gave it that so it would compare favorably with the core rules Kraken, which is a highly intelligent monster.
That said, the one in the movie seems more like a trained animal in its actions, which would indicate it's a stupid "force of nature" type horror like a seagoing Tarrasque. It all depends on what you want the critter to be.
