Hi, niki,
Try this code -
trigger opportunitytrigger1 on Opportunity (after insert) {
 list<opportunityLineItem> olilist= new list<OpportunityLineItem>();
    List<PriceBookEntry> priceBookList = [SELECT Id, Product2Id, Product2.Id, Product2.Name FROM PriceBookEntry WHERE Product2Id = <RequiredProductId> AND PriceBook2.isStandard=true LIMIT 1];
    for(opportunity op:Trigger.New){
        OpportunityLineItem oli= New OpportunityLineItem();
        oli.OpportunityId = op.ID;
        oli.PricebookEntryId = priceBookList[0].Id;
        insert olilist;
You need to replace <requiredproductid> with the product Id that you want to associate with the OLI.
