You are focusing on the "intelligent" part of "intelligent design". However, the most controversial part is the "design" part.
What evolutionists are mainly claiming, is that biological diversity results from evolution, rather than from design. And if there was no design, then the question of whether the design was intelligent is a question that never actually arises.
I'll grant that some people see an appearance of design when they look at biological organisms. I don't. It seems clear to me that evolved things are very different from designed things, and that no design, no matter how intelligent, would result in what we see when we examine biological organisms.
