The CA doesn't have anything that helps you do Lawful Intercept. They just vouch for people's identities.
If you can persuade them to fraudulently vouch for your agency as being some other subscriber then this unavoidably produces a smoking gun which everybody can see, just like when Israel produces fake passports so its agents can travel abroad to murder people.
It doesn't let them passively intercept. The CA could not, gun to its head, help you do that. The mathematics just doesn't work that way, any more than the US Federal Reserve could intervene to make three dollars twice as many as five dollars.
