The User Guide mentions several different solvers:

EnvSolver, EnvSpdSolver, SparseSolver, SparseSpdSolver, GPSolver, KdeltaSolver, and CLLSSolver

Do you have the Fortran 90 code for GPSolver? I have been working on a translation of Gilbert and Peierls original Fortran code to Rust.

Unfortunately, the performance doesn't match that of KLU. It would be interesting to read George and Liu's implementation and see if there are any improvements I can make.

I don't, sorry. It was not part of the sources I got from George.
