Most of the time, biting the hand will not be possible.

Grabbing fingers and snapping them is not as easy as you might think.

Scraping your foot down the shin may not do anything other than annoy the attacker, also in that scenario your attacker will be dragging you backwards,no balance to kick.

I would not rule out trying any of the above, just not the best options.
