I wouldn't go with a labradoodle. They are NOT hypoallergenic and they do shed. In my opinion they are also very hyper. I've met many and sadly I don't care for them.
I would go with either a standard poodle or a portugese water dog. Both are large breeds, intelligent, hypoallergenic and great with kids.
The portugese water dog's coat also grows slower than a poodle so you wouldn't have to get it groomed as often as the poodle. However, they require more exercise than the poodle. So if you are looking for a more calm breed, go with the poodle. If you are looking for a more energetic breed, the portugese water dog fits the bill.
A couple other choices...
