QGIS 3.18 does support LAS/LAZ format to load point cloud datasets. The
problem is that some installers for some platforms (most notably the
Windows installer) do not include the PDAL library needed to read LAS/LAZ
files. There is now an experimental alternative installer which includes
also PDAL library and thus it can read LAS/LAZ files too:
https://qgis.org/downloads/QGIS-OSGeo4W-3.18.0-1.msi

Please note that 3.18.0 release has been pulled back few days ago because
of several major bugs, so please consider this as a testing release where
some things may not work.

Regards
Martin
