I tried to install an additional language pack for LibreOffice 7.1 under MacOS Ventura. I downloaded
LanguageTool-5.7.oxt from here and started it up. After some wait time, this led to the error
LibreOffice requires Oracle's Java Development Kit (JDK) on macOS 10.10 or greater to perform this task. Please install them and restart LibreOffice. https://hub.libreoffice.org/InstallJava/?LOlocale=en-US
Hence, I downloaded the latest JDK from Oracle. I then restarted installation of the LanguageTool, which worked without issues.
