There are several examples of results with more than two lines, such as Youtube Studio, where a referent graphic element creates the separation without practically any visual perception problem and without using any added visual artifacts.
In the case of the question, I would try to find this referent element. I have no information about the content, but for example the date block may be an idea, all depends on the visual priority of each item.
On the other hand, not all the elements must be graphically the same, establishing visual contrasts such as the use of bold letters, fields with different graphic weight or managing well the blank spaces, helps to create well-defined compact visual limitsareas.
