Do you think that the government at any level should have any control over private and home school curriculums?

personally, absolutely not. If atheists are going to rant about the Establishment clause (which they often seem to misunderstand/manipulate and abuse) and use it to make public schools atheistic then they should leave the church schools and homeschooling parents alone, that's the flip-side of that little coin. If you don't want me and others like me "interfering" by trying to protect our children and raise them the way we see fit then fine but when I pull them out and find other means of educating them you have nothing to say on the matter.
