I'm not really sure how you're getting that transcription, I hear her say the text as written.
You can hear a number of phrases that include agus on teanglann.ie - it will sound slightly differently in different contexts, even ending up as is in some cases, just as "and" can end up as 'n in ordinary speech.
Soooooo.... I'm in the north, of USA and I hear it like this: "Lay-um Shay... Ah-gus... Lay-um-meet". I dont know where you're from....but I wonder if-- we all HEAR it differently, because of the predominance of our own environmental vernacular. If i listen to the verbal queues seven times, I may hear it differently three time. IDK....
