You are looking for impulse response (IR) / convolution plugins.
Some of such plugins:
KlangFalter from DISTRHO Ports:
https://distrho.sourceforge.io/ports.php/
https://github.com/DISTRHO/DISTRHO-Ports
Convolver reverb plugins shipped with Guitarix:
https://guitarix.org/
IR.lv2:
https://github.com/Anchakor/ir.lv2
and probably many more.
The impulse response files (the echo/reverb recorded) can also be found
online free and paid. Some may be shipped with the plugins (Guitarix
comes with 'greathall.wav' file).

I remember listening to the talk of researchers who
were traveling to
different old cathedrals, particularly to Hagia Sophia in Turkey, and
measuring echo in these cathedrals. Such buildings add a lot of deep and
very prolonged echo which depends on the building's shape and materials.
They were quantifying the noise response too.
Are there LV2 plugins that can add same or similar echo as cathedrals add?
Thanks,
Yuri
