I hope that I am just overlooking something obvious and am hoping
somebody else has experienced this before and can point it out.

A generic provider asking to perform the equivalent of a SQLTables() request is essentially just returning the data from the SYSTABLES VIEW [from either QSYS2 or SYSIBM]; i.e. just a result-set as a query of that VIEW. In effect, the DB2 for i considers the /system/ to be the /database/, thus [somewhat oversimplified,] all entities for all libraries across the system are made visible; though possibly limited only to those entities authorized to the user, AIUI, depending on which catalogs are accessed.

I have tried using a user profile that has a library list of just a
few libraries and have tried to set the default schema via the JDBC
URL. Any suggestions will be welcomed.

The Default Schema does not affect what is presented, only where certain unqualified references will search for the entity with the unqualified name\identifier.

The Job Description (JOBD) and the User Library List (USRLIBL) are primarily for establishing an interactive 5250 session. Yet even if utilized for other types of connections, e.g. ODBC\JDBC, the SQL database catalog API requests would need to be limited accordingly. However, a generic provider does not know the concept of a Library List (LIBL) of the IBM i, and presumably merely effects a query of the appropriate catalog VIEW. There would need to be an effective LIBVIEW against which the server could be requested to limit the output from the API calls [to a specific list of libraries]; see my reply referring to documentation that might assist [in part, just for IBM® i Access ODBC driver], in:
