ACOD stands for Adjournment in Contemplation of Dismissal. The case gets adjourned for 6 months and then dismissed, By accepting the ACOD, you daughter did not admit to being guilty of anything. However, it is very unlikely that she can sue. There are laws that protect stores from civil lawsuits in these type of cases and it sounds like the store had probable cause to have her arrested. It is not up to the store to decide why the items were left in the store. That is matter for the courts. However, the prescence of the items coupled with a failure to pay for them gave the store reasonable grounds to believe she stole them. Unless the facts were really extreme, I think your daugther will have to move on.

An ACoD is not a guilty plea of any kind. It is a mechanism used for cases like your daughter where no real crime took place. All her charges will be dismissed and the record sealed after six months if she complies with the court's conditions.
