If the latter, AA's CoCs are clear that they "may, without notice, substitute alternate carriers or aircraft and, if necessary, may alter or omit stopping places shown on the ticket" so I think you are out of luck getting back to BOS.

Well, not really. A stopover is a destination even on a through fare. The OP had built a proper stopover in their ticket, so BOS was a destination on the ticket and AA had to get them there. However, the OP forfeited flying to BOS and chose to come back to TLV - not sure that the airline owes a new ticket from TLV to BOS in such a case.
