Can the funds arising out of a personal injury lawsuit injury lawsuit be considered income for child support?

If the non custodial parent is past due in his obligations then yes--child support can tap the settlement to pay off the arrearages. However if the payer is current this would not be considered in annual income and therefore it would NOT pay to go back to court and have the child support adjusted as he can prove this was a lump sum settlement.

The funds coming from a personal injury lawsuit are not even supposed to be considered for taxes. I believe that it probably would not be, but the attorney working on this case can tell you. Also, if you are found disabled enough to go on Social Security, Social Security will send the child's caregiver a bit of money to assist with their care - probably not much though, unless you've worked a lot.

YEAH I THINK ANY MONEY YOU GET THEY CAN TAKE THERE SHARE AND THEY WILL GET THERE MONEY

Yes! Refer to page 23 of this IRS publication:

If it's taxable income, then it's also reportable income for figuring child support. However, in order to increase the amount you're paying, your ex-spouse must petition a court.
