Welcome to the forum. I don't know when nor do I know what art. 680 has to do with it. I do believe that the ground lug is required because of the metal threads for the screws.
If pvc conduit is used, and all grounds spliced in above ground box, No brass or steel conduit is being used, why would I need a pvc J-Box with a ground bar? I can see this only if brass or steel is used from the wet niche light to the PVC J-Box. Intermatic PJB2175 or PJB4175. I would use this box when using metal raceway. If not a standard PVC J-box ( with no lugs ) should be correct when using all pvc raceway.
Check 680.24 for the requirements for a junction box for Pool Underwater Luminaries. You will note specific specification and also the requirement that the box be listed.
Few, if any, jurisdictions accept a "off the shelf" box for this purpose.

I didn't know they made a PVC pool junction box.
You've got a large mix in wire sizes to interconnect. Will most likely have a #8 copper from the forming shell, the EGC in the light cable (probably #14 or #16), and a #12 or larger EGC from the branch circuit source. Is there a wire nut that will take that wire combination? How about a split bolt? A multi lug terminal is designed just for that type of application.
Finally, code says you have to terminate these bonding conductors on terminals.

The standard "Hayward" box is PVC -- at least the top part is. There are others, with glue-on hubs. All of them that I've seen have grounding screws or terminals to comply with article 680.

Here's a diagram showing the lugs, etc.
