As far as a lawsuit against the landowners... most states have a recreational use act which protects the landowner from such liability issues - we have it here in SD and I have never heard of someone trying to sue a landowner.
I am a little rusty on the details, but I did check this thoroughly a few years back. In short, if you give free permission to someone to hunt you are protected by Iowa law. If you charge though, lease, trespass fee, etc, then you better have some insurance coverage.
