I don't quite see the problem:

- the OSM component of a Collective Database retains its licensing terms
regardless of what you do with it.
- if you don't create a database, you don't create a database. As the
ODbL states you can use a Collective Database to create a Produced Work
without creating an intermediate Derivative Database, typically on the
fly generated results for display purposes will be Produced Works.
- if you created a dataset from the filtered results and publicly used
it, yes, likely you would have to honour a request for the OSM
component  (which naturally would implicitly contain the information
where those 4* restaurants are) TANSTAAFL.
