Can a illegal immigrant get sent back if they go to court?

If the illegal immigrant has no crimes or order of removal, the good chances are that the trip to court for the ticket would be fairly routine. ICE is currently attempting to focus its resources on certain classes of individuals and not those with minor situations as you describe. Under the memorandum on prosecutorial discretion issued in 2011, ICE has guidelines for the type of situations in which it will hold individuals. In the past, situations in which illegal immigrants went to court for any reason were always fraught with danger. Although there is still the possibility of an immigration detention hold, the chances are much less these days unless there are other aggravating circumstances.

If he faces a criminal conviction, there may be immigration consequences.  I recommend he hire an attorney who is familiar with immigration law to advice his criminal attorney before entering any plea.
