I just scanned a number of articles on the lack of a jury trial in this case. To me, the answer isn’t black or white.
I think Snopes treatment of the matter hits the high points.
It seems like part of what the suit seeks is equitable relief – generally not associated with a jury trial – and part of what the trial seeks is money damages – where they may have been able to prevail on a Motion to have the case heard by a jury (or which may have been declared to also be equitable relief by a Judge).
That’s my IANAL read on the issue, anyway:
