Well, the constitutionality will need to be tested, sure, but the US first amendment is not absolute, even if it is sweeping relative to other countries.

Just a note - most LineageOS installs aren't secure unless you re-lock the bootloader, as data can be extracted with some fairly standard mobile phone forensics kits. Unfortunately, not many devices support bootloader re-lock. The Google Pixel series is a notable exception.
