Option 3: You can try to contact google if everything I recommended to you fails. Ask google to remove your website from their search engine, but they might suggest to you what I recommended, for you to do.
It might take time, for your website to disappear, so just be patient.
Every time I take my server offline, my website disappears from the google search engine.
You would have to make sure the googlebot can't visit your website anymore, for your website to eventually disappear from the google search engine.
