Using list comprehension should work as:

new_list = [[i for i in l if i not in list_A] for l in list_of_list]

After that, if you want to remove empty lists, you can make:

for i in new_list:
    if not i:
        new_list.remove(i)

of, as @ferhatelmas pointed in comments:

new_list = [i for i in new_list if i]

To avoid duplicates in list_A you can convert it to a set before with list_A = set(list_A)
