Sacado is the AD package in Trilinos: http://trilinos.sandia.gov/packages/sacado/index.html
It works off expression templating and can be dealt with in an object-oriented code (although not optimally in my experience). If you get it working well with libMesh I would be interested in how you did it. Another question: Are you sure you need AD? If you're just trying to compute Jacobian entries and you're doing fully-coupled solves of multiple physics... you might think about using Jacobian Free Newton-Krylov (JFNK) instead. This is what we do with MOOSE. We've done some preliminary stuff on CO2 sequestration with MOOSE and it's worked well... If you're using it for adjoints / sensitivity stuff then there might be no other option....
