Is it OK to connect multiple whites and ground under the same screw into the bus bar on a panel?

Generally you're only allowed to do that if the manufacturer specifically allows it in the panel documentation or spec sheet.
If you're out of screw spaces you can run a pigtail inside the panel.

Grounded conductors need to be one per hole, no sharing.
Grounding conductors can typically share with other grounding conductors. Check the label for allowable sizes and number.
If additional spaces are needed an auxillary grounding buss bar can be added for the grounding conductors only.

My inspector once told me the panel is NOT a junction box and did not want "wire nuts" inside the enclosure.

Your inspector may want to review Article 312.8.
A problem with this could occur if the wires spliced were from the same leg of the panel. The current would be additive and could overload the wire. This is why the hots need to be on opposite legs in the multi-wire branch circuit.
