Since LVs can be referenced in a way that contains dashes, I expect dashes
may not be allowed.

See these examples:

But the following excerpt from "man lvm" doesn't support my thought.

       The following characters are valid for VG and LV names: a-z A-Z 0-9
+ _ . -

       VG  and LV names cannot begin with a hyphen.  There are also various
reserved names that are used internally by lvm that can not be used as
       LV or VG names.  A VG cannot be called anything that exists in /dev/
at the time of creation, nor can it be called '.' or '..'.  A LV  can‐
       not  be  called  '.'  '..'  'snapshot'  or  'pvmove'. The LV name
may also not contain the strings '_mlog', '_mimage', '_rimage', '_tdata',

Underscores work just fine.
You might consider using underscores instead of dashes.

As maxxik suggests, you may consider escaping the hypen/dash.
