Only if he adopts the child and he and the other parent later separate/divorce.
There may be some variable for interpretation here. If he's the child's only parental influence, and the father is unknown, a judge may order it, along with all the rights of a father.

A child support law in Illinois requires the non-custodial parent to purchase a percentage of their net income child support. The rates are 20% for 1 child, 28% for 2 children and 32% for 3 children.

The only way a mother can be forced to pay child support in any state, is if she does not have primary custody of the child. If the child or children live primarily with the father, then the mother can be made to pay child support.
Such a move will not change the amount of support owed. Illinois will likely ask Tennessee to register the support order.
Not exactly. In Illinois, child support cannot be ordered past the age of majority but "education support" can be. One or even both parents may be ordered to pay education support, based on the child's academic expenses. Education support must also be ordered by a judge, separately from a child support order.
