There are several XMPP clients trying to replicate -more or less freely- the same experiences, such as poezio [1] or profanity [2]. YMMV of course, and nothing will be a carbon copy of irssi, except if you use a plugin (but in my experience bolting another protocol on top of a client for another will result in a poor UX).

I do believe there are TUI clients for Matrix, but I am unsure of their maturity and state, or how they compare to Irssi.

I was going to say, "Have you tried poezio?".
