Almost certainly. They definitely turned over data to the US government to help them locate and connect people of interest (see Edward Snowden's revelations), some of which was very likely used to incarcerate people. Whether you consider incarceration equivalent to re-education is debatable. I find it quite likely that they also did this for other governments with less scruples about human rights.
Either way, pretty sure no US citizens have been incarcerated in political re-education camps in the USA because of data shared with any government by either Google or Tik Tok or anyone else.
If you are referencing criminals charged through the justice system, that is decidedly not the same as hunting down ethnic minorities based on their race and religion without charge or trial. You must know this.

You can be very sure because political re-education camps don't exist. There is a lot to criticize about the American justice system, this isn't applicable.
