The trainer aims for an Israeli modern Hebrew, Ashkenazi dialect. Ayin shows up as a glottal stop in that dialect (שִׁיוּר and שִׁיעוּר are distinct and used as minimal pair tests in the pronunciation trainer, for instance), but there isn't a distinction between Ayin and Aleph. I wouldn't agree that mastering this dialect makes you sound like an anglo; rather, it would make you sound like an average Israeli (and the recordings that the trainer utilizes are all made by Ashkenazi Israelis).
