Google won't react to a DCMA if it's just a link and synopsis. It has to be pretty much a whole page or at least one photo before they'll bother. This is something to explain to your client so they'll understand the approach they're asking for just won't get them what they want.
I concur with the advice to use disavow - that's what it's for. Tell your client whether some SEO added it without their knowledge or a competitor did it to sabotage them, that's what disavow was designed for. And it is, really.
One little trick I've found is, you can get rid of a lot of these links if you give a 503 forbidden access message to their bots. The bots think your site has disappeared and remove it from the directory. So that may actually get rid of some, and I'd use disavow on the rest.
