Google can DDoS?

Google has "Search by image", which takes source image from supplied URL. And other sites, like vk.com, access any URL you supply them.

Can all these services be leveraged for DDoS purposes?

The web existed before Google did. Web hosting existed before Google Cloud. I only use Google to find things that I didn't know before. If you go to /g/ and ask a question, people will normally link directly to a web page rather than a Google query.
