Also wasn't this a law firm whose data was leaked? A lot of that information is probably financial and personal records which would be massively irresponsible, not to mention highly illegal, to release in a dump.
With over 200000 shell companies created, you can be pretty sure not every shell company is involved in illegal activity. In fact, it's perfectly legal to create them, though the majority of their use cases is illegal. That still doesn't mean you can just dump private information like that on the internet
