While redeeming BA Avios for LAX-OGG-LAX on AA is the most economical method, if the OP has any interest in traveling to Europe or South America from LAX some time after returning home from Maui, AA's awards from Hawaii to Europe or South America (with a lengthy stopover in LAX) can be had for 17,500 or 20,000 AA miles, depending on final destination. (Of course, more miles would be needed to get back to LAX from Europe or South America.)
