man 8 vgcreate reads (in part):
    -l, --maxlogicalvolumes MaxLogicalVolumes
        Sets the maximum number of logical volumes allowed in this
        volume group. The setting can be changed with vgchange. For
        volume groups with metadata in lvm1 format, the limit and
        default value is 255. If the metadata uses lvm2 format, the
        default value is 0 which removes this restriction: there is then
        no limit.

Doesn't that option work for you (assuming you're not stuck on lvm1
format)? If not, where do things go wrong?

(Note that I never worry about this limit, since I never use more than a
handful of logical volumes per volume group.)
