What grounds would these large senders have to file any legal objections
against an RBL?

RBLs don't block emails.  Operators of mail servers who use RBLs block
emails (in part) based on information from RBLs.

Noone has a "right" to send email to anyone else.  Email is a
cooperative agreement between sender and receiver.  The receiver agrees
to accept the email, but at any time and for any reason the receiver can
stop agreeing to accept emails from a sender.  It is completely legal to
decide not to accept (i.e. block) emails from a sender.

RBLs are not beholden to senders.  RBLs are beholden to the receivers
who use their RBL to preserve the quality of the RBL.  RBLs are a
meritocracy.  If an RBL either lists too many valid senders or does not
list enough bad senders, then receivers will notice and stop using the
RBL on their servers.
