I'd just like to mention the lbr uitility which I found which runs under linux
https://www.svgalib.org/rus/lbrate.html
lbrate extracts/decompresses files from the CP/M LBR format. (It can also list and test such archives.) It does this in an `unzip'-like manner, mostly hiding the details of individually compressed and renamed files, and transparently deals with the required decompression/renaming.
lbrate is also (I believe) the only non-CP/M program to fully support decompressing files from all three CP/M compression schemes (Q, Z, Y). With this in mind, it can decompress such files directly, treating them as if they were single-entry LBRs.

On my github site you will find two further utilities which you may find useful. Both run under windows and linux.
mlbr at https://github.com/ogdenpm/mlbr
It supports a number of additional features as indicated below
Usage: mlbr -v | -V | [-x | -d | -z] [-D dir] [-f] [-i] [-k] [-n] [-r] [--] file+
-v / -V show version information and exit
-x extract to directory
-d extract lbr to sub directory {name} - see below
-z convert to zip file {name}.zip
-D override target directory
-f forces write of skipped library content
-i ignore crc errors
-I ignore crc errors and corrupt decompression
-k keep original case of file names (default is to lower case)
-n don't expand compressed files
-r recursively extract lbr, creates nested sub directories for -d or -z
-v show verison details and exit
-- terminates args to support files with a leading -
file+ one or more lbr, squeezed, crunched or crLzhed files
names can include * or ? wildcard characters
{name} is file with leading directory and extent removed
Listing of file details, including validation checks is always done
The -x or -d options allow files to be extracted
When files contain comments or are renamed to avoid conflicts
the details are written to a file {name}.info
mklbr at https://github.com/ogdenpm/mklbr
It supports creation of lbr files, including renaming and timestamping. Note it does not compress files itself
