Based on the available information, Lightroom does not provide a supported command-line interface for applying edits and exporting files. While Lightroom supports plug-ins, reports indicate you cannot reliably invoke Lightroom actions from the command line for this kind of unattended batch workflow.

So if your requirement is specifically to use Adobe’s RAW engine and Adobe XMP edits from a shell script, the answer appears to be no: Lightroom is not designed for command-line batch development.

Other command-line RAW tools may exist, but they generally won’t fully honor Adobe-specific XMP develop settings, since those settings are tied to Adobe’s processing pipeline. That means you should not expect tools like generic RAW converters to reproduce Lightroom/Camera Raw results from sidecars.

In short: Adobe tools are not a practical command-line solution here, and non-Adobe command-line tools are unlikely to apply Adobe XMP edits accurately.
