A number of plugins would solve this for you, most notably Zotero Integration and Zotlit. Both of these can bulk create literature notes from Zotero, using templates to define how you place and format the data in your note.
See the examples here of how that’s done for Zotero Integration, and here for Zotlit.
There’s also Zotero Sync Client that bulk imports by default.
As for other reference managers, you’re stuck with the Citations plugin, but it doesn’t do bulk literature note creation, as far as I know. Alternatively, if you can code, you could make a script that can process bibtex or JSON bibliographies.
