But should it? The host has offered TLS, Exim has tried to use it, and
received a temporary error code. There is no indication that this is the
result of a broken server. A temporary code means "try again later".
Exim has no means of knowing exactly what is wrong (it might be the
server is closing down for maintainance, for example.) I'm not sure that
the right thing to do automatically is to send the message unencrypted
in this circumstance.

If Exim gets a permanent error code (5xx) from a server, however, it
will try to send the message in clear. This is all documented in section
38.2.
