It all depends.

BB's NP reduce the enemy's "debuff resistance". So that enemy will be more vulnerable to suffer the debuff that you inflict on him. Insta-death isn't a debuff, it's just an effect. Like NP charge reduction. If an enemy is inmune to debuff, you can still reduce his NP charge. Well, the same happen with insta-death.

However, some Servants (like Shiki or King Hassan) inflict the debuff "reduce death resist". BB's NP make easier for them to inflict that "reduce death resist". However it isn't very hard to inflict that debuff on enemies, so BB's help there isn't that huge.
