IANAL but analogies rarely hold any legal water because the laws that govern each activity are completely separate.
The Missouri statute quoted above includes the 'reasonable grounds to believe that he has authorization' provision and I doubt that any sexual assault legislation would have a similar provision.
Whether or not a court would find that Google does have these 'reasonable grounds' is too complicated a question for me to more than guess at. It may be that the onus is on Google to prove that their belief was reasonable or alternatively there might be precedent about what constitutes 'reasonable grounds' that is applicable to the case.
Of course unless Google is charged with violating this particular Missouri law the question isn't particularly relevant.
When it is not necessary to make a decision, it is necessary not to make a decision.
