Hey Rand - great question.
I take some issue with using 'theistic evolutionist' to describe the group you are discussing, as evolution and universe creation are two very different things, but I get where you are coming from.
Now for my thoughts.
If a person believes that:
a) God created the universe
b) God created the universe in such a way that he knew man would evolve
Then I would say they are IDists since God explictly designed man (sure with a bunch of intermediate steps, but what's that to God)
If a person believes that:
a) God created the universe
b) God created a universe that was condusive to life, but chose to not know how it was going to end up and that mankind is just what happened based on the initial rules God set.
In this case, they are not IDists since mankind was not explicitly designed but a chance occurrence.
It all comes down to what did God chose to know. If we believe in a God that created the universe, that God exists outside of time as we know it. It/He/She would be able to see the entirety of the universe, past, present and future if wanted.
You say:
perhaps they are not teleological and think, for example, God perhaps didn't even know what would happen
This is no different then a debate about free will. How can anyone possibly believe in free will? Perhaps THEY are not teleological and think, for example, God perhaps didn't even know what would happen.
