You need to install some libraries and stuff.  Instructions are at
 but the short version is:

dpkg --add-architecture i386
apt-get update
apt-get install libc6:i386

Oh... did you already do *part* of the Multiarch setup, but not all of
it?  That would have been useful information to include.

Once the /lib/ld-linux.so.2 interpreter is there, you should get more
informative results from ldd.

This is misleading: the "command not found" refers to the "interpreter"
tasked with running LinuxSusser, which would be...

...which in your case would most probably be /lib32/ld-linux.so. You want
to have at least a 32 bit version of libc installed (e.g. libc6-i386 or
something equivalent).

I have no idea what LinuxSusser is, but whoever you got that from should
be at least as fair to tell you what packages/libraries it depends on.

It starts on my "bookworm" machine.
Your executable probably got corrupted somehow.
Try to download it again from author's website [1]. There you will find 
a link to DropBox file sharing service.

Install dependencies (64bit and 32bit) for this program:

   $ sudo apt install libglib2.0-0 libpango-1.0-0 libatk1.0-0 openssl
   zlib1g libexpat1

   $ sudo apt install libglib2.0-0:i386 libpango-1.0-0:i386
   libatk1.0-0:i386 zlib1g:i386 libexpat1:i386

A normal output from "ldd" and "file" for reference [2].

Have you tried running a 32-bit app that was installed via apt/dpkg ?

If not, I'd recommend installing a simple 32-bit app.  Two things that may 
happen:
* it may cause the package manager to install some other packages that will fix 
the problem affecting 32-bit LinuxSusser.
* after installing the 32-bit app, that doesn't run either, in which case 
investigating why the fully-debian-supported 32-bit app doesn't work, may be a 
useful next step.

For simplicity's sake, I'd recommend a 32-bit package that you don't already 
have a 64-bit version installed for, that also has very few dependencies.

Some candidates I would suggest are:
ftp
dc
lsdvd

I strongly suspect there's at least one of those three that you don't already 
have installed as a 64-bit package, and all three have relatively few 
dependencies.
