Update:
The optical transient AT2019lvs is now reported seen by PAN-STARRS 18 hours before the GW event. There is also a faint possible precursor visible on the SDSS image so most likely just a CV and not associated with the GW event see GCN 25204

I also see that it is now reported outside the updated region of the sky
https://gcn.gsfc.nasa.gov/gcn3/25207.gcn3
and as I type, spectroscopic confirmation that it is indeed a CV
https://gcn.gsfc.nasa.gov/gcn3/25209.gcn3
so a false alarm this time I am afraid
