[BUG] @* in [cite/nocite:@*] is a valid special LaTeX bibliography key, but it is highlighted using "error" face by oc.el (was: [PATCH] oc-csl: Add support for nocite citations)

Thanks for the clarification!
Then, oc-natbib, oc-biblatex, and oc-csl should be modified to provide
an alternative activation function that will not highlight @* as
non-existing key.

Probably, we can even use an alternative "special" key face, not
'org-cite-key.

Best,
