Get a ride - i guess if someone owes you a big favor you can force them to come back from LAX around 5 pm
Rental car is the only option but you'll need to check on price

Public transportation to LAX from Irvine is pretty straight forward. Get your sister in law to dropped you off at Irvine Metrolink Station and take the FlyAway Bus. It's a bit pricey but it runs like clockwork using the carpool lane on I-405.
The other thing I noticed is the OP is traveling with his wife... that means you can use the carpool lane if you have a rental car.
Supershuttle is not reliable and not recommended if time is valuable.
I would definitely leave by 3pm no matter what method of transportation you use. I-405 north bound shouldn't be very congested from Irvine but there is currently construction at the 405/605 junction and traffic backs up for about 5 minutes when there is otherwise no congestion. You
will encounter heavy traffic from about Artesia Blvd (route 91) to I-105 by 4pm as you make your way closer to LAX. The early shift workers at the aerospace companies in South Bay area leave their office around 3:30pm and they generally head north towards West LA or San Fernando Valley.
Edit: I just noticed FlyAway has cut back the Irvine bus frequency significantly... oh wells...
