And a forcefield would do all of that. Which leads back to the original question; is outright stopping a giant snake with a forcefield displacing the snake, or is it blocking the snake?

Molecular-level science talk will get us nowhere, as not only are there are no giant snakes on the molecular level but the definitions of combat terms are not determined by going all the way down to a molecular level and examining the mechanics behind the term on said level. If they were, we would not have terms like "hit" or "grab", but instead things like "repel with great force" and "partially surround".
