My rabbits will go hang out two floors above me and ignore me when they are out. I think they like the freedom. They know they don't have to let me pet them or pick them out. When they have so much room there is so much to explore and do. My one rabbit Chase, will ignore me all day. But then at a certain time around 6-7 pm she will come back downstairs and want pets. My other rabbit, Little Bunny, is just happy to run around and play and usually prefers that I leave her alone. I think it is just a difference in personalities.
Even though Little Bunny would never let me pick her up when she is running around the house, if she is in her cage she will because she knows she has no other choice. I only do that to cut nails or give meds. But she knows she can't get away.
How long have they had free run? They still may be so excited about the new freedom, pets are not a priority. I would just go with the flow. Try to get down on the floor near their favorite hang out spot and see what they do. Though it could take sometime.
I do think personalities can change throughout a rabbits life. When Chase was younger, she never wanted pets. She was to busy tearing up boxes and playing. Now, in the evening she expects them and would let me pet her till my arm fell off, but only during the evening. Otherwise she runs from me.
