If there was an investigation, I suspect the ATCO would be asked "Why did you choose the downwind runway?"
If he had good reason (company noise abatement policy, lots of traffic from west and long dry runway) then OK, otherwise he might get part of the blame.
Ultimately it would be up to the pilot to say "I can't accept 27, need 11" and therefore his fault. The pilot is in charge.
MDH - not our concern. We don't know the pilots minima, and its up to him to ask for a different runway or divert if he can't make them.
