technically speaking, anything that can change the click-through from the SERP to your site, such as changing the snippet, can have an effect on ranking.
i doubt that google would deliberately provide documentation of techniques intended to hurt your ranking such as how to "Prevent search engines from displaying DMOZ data in search results for your site":
i think what you are really asking is if meta robots NOODP is a form of link disavowal.
google might be vague in their answers but they are rarely shy about indicating that there is risk in certain techniques and i see no sign of that with NOODP.
