in your two cases, if, in your opinion, the players committed a foul and you viewed the contact to be excessive, you can charge an intentional foul. You can replace "even though the opponent is playing the ball" with "even though the opponent (offender) is dribbling the ball" or "even though the opponent (offender) is trying to set a screen." the key operative phrase here is "judged to be excessive" even if the play did not otherwise rise to the level of being considered to be intentional.
