I will use exiftool for geotagging many pictures using a kml file. Is there any option on command line for tagging only pictures without any existing geotag? I do not find any information about it.

I would simply check to see if there already was a Latitude (or Longitude) by adding
-if "not $GPSLatitude"to your command.Change double quotes to single quotes if you're on Mac/Linux.
Another option would be to instead add
-wm cg. That means that exiftool will not try to overwrite tags that already have data.
