The guide I am using says removing the air injection system is optional. How would I go about capping it without having to remove the rail? Thank you

cap the hard pipe feeding the injector rail from the smog pump. Looking at the pictures provided above, i do not see the air injection hard pipe in the pic. Could PO removed it?

I thought that was what that valve looking think with 3 black hoses running off it was…

It’s possible. PO had a shop do an engine swap and already rerouted the belt off the air pump so it’s not functional
 
The pipe looks like this:

Probably the PO made the proper fix - removed the pipe and capped the air injector holes with genuine Toyota caps. If not this is their PN: 90340-14001.
