First, it's debt, not deficit.  Pretty important distinction.
Second, your figures are way off. By tens of millions.

Brother Pakuni:

Whether it's a deficit or a debt, it's a shortfall that will either have to be made up by the taxpayers of the State of Illinois or through astronomical returns on
existing invested funds.

Secondly, assume I am off by tens of millions. Let's assume it's $100 million. That's 50 basis points, which in the greater scheme of things, is nothing!

Telling government workers, "we'll cover it later" is bad policy, as Illinois has shown.
