KML is expecting latitude-longitude formats, but you seem to be in a 
projected location.

Try this:

1) Create a new lat-long (in degrees) location with region suitable to 
your map.
2) Start Grass in the new location.
3) Use v.proj to transfer the old map into your lat-long location. Eg:

v.proj input=<your map> location=<old location> mapset=PERMANENT

4) Try running v.out.ogr from there.
