What’s the advantage of using items as opposed to, for example, directly accessing the dictionary keys and values?

for company in biggest_brands:
    print(company + " has a value of " + str(biggest_brands[company]) + " billion dollars.")

Is it simply about readability?

Perhaps, and it may have to do with redundancy.

for company, value in biggest_brands.items():
    print (f"{company} has a value of {value} billion dollars.")

That is easier to read and comprehend, especially since it uses named values for company and value.
