In the REST API response, Lookup column looks like following

{Internal Name of the column} + Id

Let's say lookup column name is Person, so it will PersonId in response. Now you can apply filter on PersonId column.

var query = "/_api/Web/Lists/GetByTitle('List Name')/Items?$filter=PersonId eq null";

To know more about $filter, you can follow my article
