What is the ruling on food products containing the substance sucralose (Likrol), and is every chemical substance ending in "ol" and containing a hydroxyl ion (OH) considered intoxicating?

If Lecrol contains intoxicating alcohol, adding it to food has two scenarios: First, if it is added while it is intoxicating, then eating the food is forbidden due to its impurity. Second, if it is added after it has transformed into a non-intoxicating substance, then eating the food is permissible due to its purification through transformation. The default for things is permissibility and purity until proven otherwise. As long as you doubt its intoxicating nature, there is no harm in consuming the foods. It is advisable to ascertain its true nature to remove any doubt.
