TopoTools version 1.9 is scheduled to be released with VMD 1.9.4 (if that ever gets released, that is).
Version 1.9 adds support to typelabel maps in LAMMPS via topo readlammpsdata
and topo writelammpsdata
with the new keyword typelabels
added for the latter (without the option, old style numeric types will be used).
This corresponds to the typelabel implementation in LAMMPS version 15 September 2022.
