An awful lot of EULAs (software or otherwise) include odious clauses or terms easily misused. I daresay even most, since US and international contract law is heavily biased towards industrial corporations being permitted to include and enforce such terms.
Often, court cases are about arguing that a clause in question is, in fact, odious and unenforceable without causing undue suffering.
If the patient dies or suffers permanent health effects from the extraction surgery, I anticipate a wrongful death lawsuit may well follow.
