KML has very limited styling abilities compared to SLD, in particular, its
styling language misses dashed lines, see reference here:
https://developers.google.com/kml/documentation/kmlreference#linestyle

If we are thinking about a KMZ containing a straight KML file with actual
features inside, then scale dependencies are lost too, because KML generated
by GeoServer does not have a notion of scale dependencies either (I guess
it could be mimicked by attaching a Region with a LOD to the KML elements,
that has not been attempted but given funding it could be implemented).

GeoServer normally addresses this by using a heuristic, returning a KMZ
with network links back to the server which will return dynamic content
based on the zoom level, either an image overlay or straight feature, and
that has some ability to retain scale dependencies.

I cannot comment more on your case since you haven't shared the link used
to produce the KMZ (there are a lot of options), but
long story short, some styling features are not available in KML and others
can only be mimicked if you choose certain generation options
(e.g., if you use the "download" mode then scale dependencies are surely
getting lost).

Cheers
Andrea
