Yes, this is a free offering that customers will receive by default. Admins can always choose to adjust knowledge sources enabled in their workspace under settings.
Q: Is the US Case Law knowledge source meant to be a full replacement for other legal research databases?
No, this is meant to be a complement to other research tools users rely on. Generally, users can use the US Case Law knowledge source for initial queries, as well as embedding in other Harvey platform features outside of Assistant.
