There are raster LiDAR modules (r.in.gdal, r.in.lidar, r.in.pdal) and the
latter two work with .las files, so I assume that my data use r.in.gdal.
It's been a long time since I've build LiDAR maps and I ask for the proper
command lines to 1) set the location for import and 2) import the data. An
example file tree is 10,008 lines long and downloadable (for 5 days) from:

TIA,

For now, I'm interested in only the bare earth data; learning which files to
use for the other data is still valuable.

Peaking at the file list you provided, you are dealing with already
processed LiDAR data in raster (and shapefile) format. Thus r.in.gdal
is the way to go.
r.in.las (obsolete) and r.in.pdal (the new way to go) deal with raw
point clouds in LAS format. They perform point binning according to
chosen criteria to generate a raster.

Māris,
Thanks very much for confirming what I thought was the case.
Much appreciated,
Rich
