Can I use this card's [Main] effect to return Digimon cards from my opponent's trash to the bottom of the deck until the total of their levels is 8 or less?

No, you can't. A "by doing X" condition can't be met if only some of the required actions are performed. In the case of this card's [Main] effect, you must return Digimon cards to the bottom of the deck until the total value is the specified level.
