ELI5; If the pressure deep under water is so extreme that it would kill most animals, why are a lot of the creatures we find around the deepest parts so soft? (Squids, blob fish, some jellyfish, etc)

They may be soft, but they're also filled with the same substance *making* the pressure; water. Thus, the pressure essentially "passes through" them and doesn't affect them at all. It would be absolutely unreasonable for an animal to try and "resist" the pressure, because it is such a vast force that they'd be completely crushed. But as long as they don't try to keep a lower pressure inside of them (e.g. a bubble of air), there's nothing for the pressure to compress.
