This answer is not directly usable under Arch, since I don't know the tools there.  I show you a way to do it on Debian, which may inspire you to find a similar way in Arch.

With *apt-file*(1), you can list the files that a package provides.  From that list, you can see if the package provides files in `/usr/bin/` or in `/usr/lib/`.  It's not a perfect approach, since it may provide files in both, in which case you're on your own.  Of course, in Debian it would be easier, as libraries are names using `lib*` for runtimes, and `lib*-dev` for development files, but this is just for demonstration of the technique.  Also, it's not always clear, as some packages provide bith libraries and binaries.

```sh
$ apt-file show libncurses-dev | pee "grep -m1 '/usr/bin/'" "grep -m1 '/usr/lib/'"
libncurses-dev: /usr/bin/ncurses6-config
libncurses-dev: /usr/lib/valgrind/ncurses.supp
$ apt-file show libncurses6 | pee "grep -m1 '/usr/bin/'" "grep -m1 '/usr/lib/'"
libncurses6: /usr/lib/x86_64-linux-gnu/libform.so.6
$ apt-file show libbsd-dev | pee "grep -m1 '/usr/bin/'" "grep -m1 '/usr/lib/'"
libbsd-dev: /usr/lib/x86_64-linux-gnu/libbsd-ctor.a
$ apt-file show libbsd0 | pee "grep -m1 '/usr/bin/'" "grep -m1 '/usr/lib/'"
libbsd0: /usr/lib/x86_64-linux-gnu/libbsd.so.0
$ apt-file show coreutils | pee "grep -m1 '/usr/bin/'" "grep -m1 '/usr/lib/'"
coreutils: /usr/bin/[
$ apt-file show pass | pee "grep -m1 '/usr/bin/'" "grep -m1 '/usr/lib/'"
pass: /usr/bin/pass
```
