Which Agency Holds a Report from Joliet
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
Inside Joliet that is the agency that reports to the FBI for the city (filed by the FBI as Joliet Police Department); outside it, the Will County Sheriff's Office.
The FBI's agency list also places three campus police departments and three other agencies in Will County, each with a records office of its own.
The Orland Park Police Department, the Tinley Park Police Department, the Park Forest Police Department and seven more are each listed by the FBI across several counties including Will County, so their arrests are not broken out for Will County here.

What the Illinois Freedom of Information Act Requires
Under the Illinois Freedom of Information Act the agency must answer a request within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages. The request goes to the agency that holds the report, in writing, and does not have to say why the report is wanted.
Any other county record goes through the county records request page SearchSystems verified, at willcountyclerk.gov/general-services/freedom-of-information-act-req... (page title: Will County, IL Elections).
A defendant who has been charged gets the report through the case: the State's Attorney handles discovery for pending cases.
