No, Aulani does not off any shuttle or excursions. They do have an excursion company that works with them and there is a representative in the lobby of Aulani, but Aulani has nothing to do with them and you have to pay the tour company separately. Since Covid, many of the tour companies no longer provide transportation. You would have to contact them directly to find out if they are offering it again. They were not as of a couple of months ago. You need a car. Aulani is not close to anything and ride share is very unreliable and expensive. I always tell people to look at your trip as a vacation to Hawaii, with Aulani being the hotel where you are staying. Get a car for your stay and go out and explore.
