I have opened an issue on the LedFX github and they don't seem to be the authors of the aur package.

https://github.com/LedFx/LedFx/issues/304#issuecomment-1423339854

Lets see if the author responds soon and can update the package.

Hello,

The issue here is, you got to give the current maintainer time to solve
it themselves, you are not the maintainer of this package, and you can't
request an orphan because you want to own it.

However, you could request the maintainer to add you as a co-maintainer.

Otherwise your only option is to prove the current maintainer is not
actively maintaining the package, and thus warrants a orphan.

Hope this help,
