I was under the mistaken impression that they needed people like me. All they really need is my material. As an actual human being I am just another mouth to feed.
Not even that, actually. Individually, we don't even exist for Google. They are simply not interested in anything that doesn't scale, and individuals don't scale. Heck, they didn't even want to offer customer service because Larry Page felt it was an outdated model that didn't scale (and only reluctantly got dragged back into the modicum they now offer) (See Levy's book "In the Plex" - you probably won't like what you read, but you might better understand where Google is coming from)
I absolutely sympathize with your ongoing battle, but waiting for Google to fix it just isn't going to work. You can take them to court, and maybe you will win, but they have enough lawyers and devices to drag it out forever, so it might end up costing you more than you get. If you win.
Some business models just aren't made for search engines. I would venture to say that making art that people love to steal would be one of them. If it were I, I would get all those images behind a password, or at least the high quality versions of them.
You could take a look at how the stock photo companies deal with it.
I'm not sure what your exact business model is, but alternatives might include mining your past customers via email newsletters, offering only watermarked "tastes" of the art/fonts on your website, requiring people to create an account before viewing them full size, print advertising, subscription models, social media, affiliate programs, etc.
I dunno, maybe you can use a slideshow or video presentation that can't be captured at full high quality resolution.
Google is Godzilla, and we're the collateral damage getting smushed between its toes. It doesn't even notice.
