That's a great question where there's not an easy answer, to be honest. Choice of law (the question of which state's law apply) is a complex field with each state having its own rules as to how it decides. It's also a separate question from where you can sue for a particular thing. So it's difficult analyze either question in the abstract.

(It took me a while to understand what was being said here: in case it helps anyone else, there is a line break inside of a hyperlink inside of a footnote that is spreading the hyperlink across an entire page of PDF content somehow, so very little is visually wrong--it isn't that page 27 is showing nothing but a link, which is how I initially interpreted this issue report--but the behavior is very wrong: all of the text on page 27 acts as the link.)
The DMCA isn't relevant if you host your own website - they could sue you for copyright infringement, but that seems unlikely. Of course, IANAL.
As a commenter below said, you would be the one taking the risk, but it would add a huge amount to the credibility of your claim if you posted the legal notices.
