InCan they be charged with anything besides the known $100k penalty for openly deciding to break the law?
The answer may depend on US state-specific legislation but In england-and-wales - which is also a Common Law jurisdiction - the demolition of a listed building without proper authorisation is an offence under s.9 of the Planning (Listed Buildings and Conservation Areas) Act 1990
(1) If a person contravenes section 7 [ie demolish, alter etc without authorisation] he shall be guilty of an offence.
...
(4) A person who is guilty of an offence under this section shall be liable—
(a) on summary conviction, to imprisonment for a term not exceeding six months or a fine, or both; or
(b) on conviction on indictment, to imprisonment for a term not exceeding two years or a fine, or both.
(5) In determining the amount of any fine to be imposed on a person convicted of an offence under this section, the court shall in particular have regard to any financial benefit which has accrued or appears likely to accrue to him in consequence of the offence.
It will depend on the circumstances and the evidence, but one potential scenario is for both the company officials and the company itself (as a separate legal entity) to be prosecuted - obviously a company cannot be sentenced to imprisonment.
