"Well... if it helps, I've never heard of anything like that here. And I'm pretty sure LIEs can get blood for you so that wouldn't be an issue." It's not exactly great for them if everyone turns into mindless killing machines, after all.

There are obvious questions in there, about what kinds of things Shido did before, but this does not seem like the time for them. And in reality, Phillip probably doesn't really need to know, willing to bet Shido feels terribly about it without any probing. For people like him... maybe Duplicity is a genuinely better situation.
