In 93-94 at the age of 28, Pippen averaged 22 points, 8.7 rebounds, 5.6 assists, 2.9 steals, and 0.8 blocks. That season is of note because it is the one full season Pippen had in his prime when he did not play with Jordan. It is also his career high in all but assists and blocks. While those are nice numbers, they aren't anywhere near Lebron James numbers.
Lebron is pretty much a better defending version of Oscar Robertson. That is his closest comparison. A guy that was bigger, stronger, faster, and just better than the men guarding him, who could score from anywhere at an obscene efficiency, pass like almost no one before him, rebound better than anyone else at his position, and generally just take over a game at any time.
