Warning: Please include a link to the DD script in question in your post. See this thread for the proper posting format when asking a question.
You should be able to modify any of the RSS scripts on DD to remove the actual link to the feed story, by editing the .js file. But in terms of static display, gAjax RSS Feed Displayer would be the closest out of the box. To remove the link, inside its .js file, find the remove the part in red inside the below line:
Code:
var itemtitle="<a href=\"" + feeds[i].link + "\" target=\"" + this.linktarget + "\" class=\"titlefield\">" + feeds[i].title + "</a>"
