If there is no Digimon card with the [Xros Heart] trait among the three revealed cards, can I still play [Taiki Kudo] from among the revealed cards?
Yes, you can play [Taiki Kudo] even if there isn't a Digimon card with the [Xros Heart] trait.

This card's [Security] effect reveals 3 cards. If both a Digimon card with the [Xros Heart] trait and a [Taiki Kudo] are among the cards revealed, can I choose to only activate the effect that adds the Digimon to my hand and not play [Taiki Kudo], or the other way around?
No, if you perform any of this effect you must perform as much of it as possible, so if both a Digimon card with the [Xros Heart] trait and a [Taiki Kudo] are among the 3 cards revealed, you must perform both "add [...] to your hand" and "play 1 [Taiki Kudo]," or you must choose to perform neither.
