Currently Solidus does not support the legally mandatory fields on a per store basis.
In addition there are schema.org structured data sets that could be used to provide such information for SEO benefits.

Current behavior
No information can be provided from the store resource apart from rudimentary SEO data and store name and description.

Expected behavior
Any store should contain a base line of legally required data to be augmented where necessary with pages for the specific jurisdictions.

Additional context
Example Germany: Pflichtangaben
