If LA-120's jog DTR when they *transmit* a ^D I'd call it a bug.
Terminals like TTY-43's did lower DTR when they *received* ^D's,
but transmitted them without a wimper.  The V7 UNIX tty driver
(ah, the old days!) would inhibit echo of the ^D when in COOKED
mode, allowing the hoards of TTY's around Bell to send ^D's with
impunity.  The much-maligned 4.1BSD tty driver preserves this
tradition.

CBREAK and RAW mode are another matter--^D's are echoed just fine
in these modes.  Could it be that you are in one of these modes
when you sign off?  Or (gasp) half-duplex?  Or is the LA-120 that
brain-damaged?
