Looking at the source code for db.out.ogr, I see that this module has a somewhat strange approach to checking for the overwrite flag. There is a test for existence of a file with the same name as the GRASS *input* layer, but with .dbf extension. If such a file exists, the module fails, as you saw. I can only guess that this unusual test was implemented to avoid overwriting the *.dbf component of a shapefile. That is, when saving an attribute table to a dbf file, if there was a shapefile with the same name, then it's dbf component would get changed, corrupting the whole shapefile. I think this could be done more simply. (I'll suggest a PR)
In your case, you could get around the issue by simply adding the overwrite flag to your command. Since you're saving to a *.csv, there's no danger of overwriting any existing dbf.
