You show that you don't understand the reason for this. This is a
shared library that is linked with another system library: Pango. It
results in an automatic 'Requires' on the libthai library SONAME in
the pango package, since the library is required at run-time and
isn't optional.
$ repoquery --whatrequires libthai.so.0
libthai-0:0.1.9-4.fc9.i386
pango-0:1.20.4-1.fc9.i386
libthai-devel-0:0.1.9-4.fc9.i386
scim-thai-0:0.1.1-2.fc9.i386
pango-0:1.20.1-1.fc9.i386
Pango in turn is required by many a dozen packages. Removing Pango
creates a long dependency chain of packages that would need to be
removed, too.
In case you want to remove a system library like LibThai, you would
need to disable it in Pango -- or rewrite Pango to load the library
as an optional plugin (that's likely harder).

I fully understand what caused this.
My next question would be : "what would happen if such a helper program
for every small lanquage were included in the same way?"
A better solution is needed for this kind of things.
