Query Syntax With LIKE

I have a variation on a question I asked earlier .  How do I use LIKE in the following query and then in creating the variables?
Line 7 and Line 20;

 	$check_alt  = 	"SELECT meta_value, meta_key
					FROM wp_woocommerce_order_itemmeta
					WHERE (meta_key = 'Bicycle Info - Primary Operator First Name'
					OR meta_key = 'Bicycle Info - Primary Operator Last Name'
					OR meta_key = 'Bicycle Info - Bicycle Serial Number'
					OR meta_key = '_line_total'
					OR meta_key LIKE 'Custom Price - Bicycle Liability %')
					AND order_item_id = :order_id ";
 	
		$checking_alt = $pdo->prepare($check_alt);		
		$checking_alt->execute(array(':order_id' => $order_id)) or die(print_r($checking_alt -> errorInfo()));
		$res_alt = $checking_alt->fetchAll();	
				
				if ($res_alt) {
					
					foreach ($res_alt as $rows)  {
						if($rows->meta_key == "_line_total") { 
							$total = $rows->meta_value;
						}
						elseif($rows->meta_key == 'Custom Price - Bicycle Liability')	{
							$total_liabil = $rows->meta_value;
						}			
						} 						           
					}		
				}	
			}
