It appears that the promo cards for the LoTR CCG series were issued in "blocks" over a several year period to promote certain events. They were distributed at local game stores, conventions, tournaments, and as magazine inserts.
Based on the fact that these weren't released in booster packs and that they are not associated with a particular expansion set, I suggest a single, multi-year set with one checklist. Similar to how Pokemon "Black Star Promos" are listed.
This isn't a complete list, but here's the "blocks" that I have been able to find and when they were released.

Many of the cards are stamped with the event that they were promoting.
For example (DGMA Territorial Open Championship)
Return of the King movie promo:
My two-cents is worth slightly more than a penny.
