"Usually a sexual assault occurs when someone touches any part of another person's body in a sexual way, even through clothes, without that person's consent."
A forced kiss could definitely be interpreted in that way, especially after being told to get lost.
The involvement of 'sex organs' is optional.
Let's parse that statement that you quoted:
> Sexual assault is any type of sexual contact or behavior that occurs without the explicit consent of the recipient.
Lack of consent: check
Sexual contact or behavior: check
Note the 'any type'.
> Falling under the definition of sexual assault are sexual activities as forced sexual intercourse, forcible sodomy, child molestation, incest, fondling, and attempted rape
Force: check
These are things that definitely fall under the term sexual assault, and a kiss goes quite a bit further than 'fondling', especially if it has already been indicated that such a kiss - and then there are kinds of kisses - is not welcome.
If I was on the defending side I'd hate to have to try to present the McClure case in a way that it might end up in this bracket, possibly that list is exhaustive and as long as the word 'kiss' isn't in the list you might get into 'sexual battery' but frankly I think that's just terminology, if the lady felt assaulted I don't fault her for picking the wrong narrow legal term and I suspect that in plenty of places the judge would see it in the same way.
