No, bivariate Moran's-I and LISA are not available in ArcGIS. However the Python library PySAL (http://code.google.com/p/pysal/) does have these statistics available, so could plausibly can be coded as a ArcGIS tool. Some alternatives are the spdep package in R or the GUI software(s) OpenGeoDA (http://geodacenter.asu.edu/) and PASSaGE (http://www.passagesoftware.net/).
