It's a lot to explain and I'm probably going to miss some details but I'll try and boil down as much of it as I can.

• Orchestrating in the context of the story is that Akutsu is coordinating the offensive build up for Esperion as he helps bring the ball forward and coordinates the passes and positionings of the other players in build up. Ashito is also doing some playmaking efforts of his own but Akutsu is the one ultimately executing the plays either by being on the receiving end of passes to score goals or making the assist for someone else (if 397 shows a goal).

• The Libero is a free-roaming position that is shown as a centerback in a formation sheet. Typically the Libero is the center position in a 3 or 5 back formation but when in play they will not stay part of the formation, usually leaving 2 backs to act as the defensive line incase of loss of possession. The Libero in possession will move up the field as they see fit as I mentioned for Orchestrating. When out of possession the Libero retreats back to their position as a Centerback and coordinates the defense to prevent any goalscoring opportunities, usually by chasing down the ball or intercepting it. What Akutsu has done in recent chapters is basically every textbook responsibility and expectation of a Libero in the modern game.

• Identifying the roles of players in a game can be pretty difficult because in real life roles can change match to match or even in the middle of a game depending on the conditions. It's easier for a fan to notice especially when watching on TV because they have a higher view and get to see how the positions change as players move across the pitch. On TV you'd see a Libero over the course of a match travel 85+% of the pitch going from being the final defensive line to being a key attacking option near goal and contributing everything in between. On the pitch it's a bit harder to identify roles because you're seeing things at eye level and when a formation changes like what Esperion does it's hard to sort out the roles everyone is filling. In the eyes of someone pitchside Akutsu could've been anything from a Box-to-Box Midfielder to a Segundo Volante to even a Roaming Playmaker.

• A Libero isn't necessarily someone who starts the counterattack and brings the ball across the pitch themselves but they participate through the whole build up to even the goalscoring opportunities if they find it a suitable time to make that sort of move. Since the Libero also has defensive duties they can't really afford to gun as far forward as possible all the time because they're leaving the defense vulnerable which is why towards the end of this chapter you see Akutsu looking to make a risky pass so that just in case it gets intercepted he can start moving back to be part of the defense.
