So i traced the error to my access log and I found that these errors are being caused by some site requesting a file that no longer exists

While this issue is being worked out, you should either block the offending site(s) from attempting to accessing the non-existent files, or you should do a 301 redirect of the moved files–or at least the moved directories.

Furthermore, you can block the Googlebot-Image bot in your robots.txt file. Although the image bot should not be causing the issue since it is just searching your site gathering information. It is not requesting files, it is discovering them.
