IP Lawyer here - no, it's not plausible.

Copyright is strict liability. You do not have to have knowledge or intention to violate copyright, that only goes to the types of damages.

Unintentional copyright violation, or believing you have a license, is not a defense to infringement.

I have no idea what you mean by "under the DMCA and other sources of law it is plausible". The DMCA is irrelevant here, and you give no "other source of law".
