I guess "all" and "all of" mean much the same when followed by a vowel. I think I picked "all of" because the extra syllable makes a better rythm, no for anything to do with meanings, so as this isn't a poetic or singable translation and you would prefer it without "of" I'll make that change.

But "te siento" only means "I feel you" in phrases like "I feel [that] you are adjective" ([that] is optional in English, and English can often omit "are" but it can't admit the adjective (which may be a phrase or a singe word). Sentir with a person as direct object without saying what is felt can only mean hear, see, or smell - it can't mean feel (note that the direct object of "I feel that you are tall" is not "you" but "you are tall"). There's no explanation of what is felt in the Spanish, so the verb can't mean "feel". Maybe "hear" would be correct in this song, that's not obvious from the lyrics but given that there are lines for each singer plus lines for both singers it could make sense when hearing the song. Translating "yo te siento" without any following adjective as "I feel you" is just plain wrong, the sort of thing that Google Translate (and other machine translations, like Reverso Context) do (with the result that people who use GT etcetera end up getting things wrong).

If you look at the dle.rae.es page for sentir you'll find 9 ordinary uses of the verb and some reflexive uses (which aren't relevant here because "io te siento" is not reflexive) and you'll see that none of the ordinary uses described allow a person as the direct object of sentir exept when it means hear/see/feel. The nearest equivalent I can get for that in English is to use "sense" - "I feel you" tends to mean something quite different ("yo te toco").
