Presumably "LAEA" = Lambert azimuthal equal-area projection, in which case it has no standard parallels. The question would be where to center it. That's an easier problem to solve in the typical case than Albers; you simply find the small circle that circumscribes the area of interest. That small circle's center coincides with the center of the optimal Lamber azimuthal equal-area for the region.

By the way, do you have a similar algorithm for optimal parallels for the
