I was watching MLB Network in the top of the 9th. The commentators (FWIW) didn't hate not walking the bases loaded, though they leaned that way. They said the thought process was that you'd rather take your chances that the game might get tied up when your team hits in the bottom of the inning than risk the Cubs taking the lead with a bases loaded hit. The way the infield was aligned, the Brewers were conceding the run in the middle of the infield, but coming home if it was hit to the corners. Basically, trying to avoid the big inning while still having the chance to win the game outright. Whether or not one agrees, that was likely the thought process.
