MarsSeed [1] filed a deletion request for onnxruntime-cuda-bin [2]: Not actively maintained on AUR; currently several point releases behind the newest release. Also, upstream's build is insecure, with executables having RPATH entries for dirs in /usr/local, and lacking RELRO.
But this package is no longer needed now that Arch extra repo carries the latest version of onnxruntime-cuda. [a] [a]: https://archlinux.org/packages/?q=onnxruntime-cuda [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/onnxruntime-cuda-bin/
