According to the episode that aired, Jill went to the hospital only sometime the night that Izzie was delivered. It was only a relatively short time. She may have been admitted late one day and delivered just into the next day. Granted she might have always needed c-sections, but if Izzie was transverse all along, if she'd had competent care then she could have saved herself needless laboring and taking castor oil and so on. (Sunday 10 pm to Monday 12:45 AM for instance.) Trying VBAC at home with Sam was flat stupid. If she wanted to VBAC, which is a fine idea, she should have followed recommendations and done it in a hospital with competent actual medical supervision.
