Yeah, my example is clang-tools
yours is clang-tools-8.

clang-tools is the meta package which will create the symlink. The actual binary is clang-tools-8.

On apt.llvm.org, I am always point to trunk (modulo a few days latency).
On Debian & Ubuntu, depends when these distros are shipping.

You can still use old versions by using /usr/lib/llvm-X/bin/clangd
