Phages are easier to manufacture, and more expensive to deliver, than antibiotics. They target very specific bacteria. Instead of identifying the bacterial strain (which if I'm not mistaken is done using phages), a cocktail of phages would be administered. Even if that doesn't work, finding a strain of bacteriophage from the environment which does kill the bacteria would still be quicker than developing a new antibiotic.
