I have a 2 part question. I have a The One Ring from the LTR Bundle. It is foil.

1. Were non-foil versions of this art created? I see some on TCG, but not many so it could be a mistake.
2. When adding cards that only come in foil (like this ring) to my collection, should I add the "Foil" modifier? With and without the Foil modifier have slightly different deckbox prices and match with different traders.

The bundle copy is the foil, and you need to select the foil treatment when entering it. It should be cheaper than the variant that is not foil. The non-foil bundle art was available in collectors packs.
