Update: I have tested how this mod interacts with several faction mods. Mod list:
"istl_dam",
"diableavionics",
"DisassembleReassemble",
"fleetdialogue_morro",
"lw_lazylib",
"MagicLib",
"nexerelin",
"ORA",
"TS_Coalition",
"shaderLib"
For those mods who implement their own dialogue, that dialogue will not spawn this mod's dialogue options. A couple examples: Coalition, Dassault-Mikoyan Engineering
However, mods that use the standard default fleet dialogue from vanilla for their mod faction will have the options populated. Example: Diable Avionics
I could not test Tiandong Heavy Industries because the mod plugin is set up to crash the game if Fleet Dialogue is active, so that is one way a modder can easily get around this. Another way would be to just implement custom faction dialogue using the unique mod id to prevent the default vanilla dialogue from being used.
Now, in general I see no easy way around this on my side since the majority of vanilla factions rely upon the defaults, but as an olive branch if there are particular modder/modders who really don't want to add custom dialogue for their faction or an exclusion in the mod plugin and also don't want these options available: Post here with a link to the mod page and I will try and add a "not this faction" check to the defaults and I *think* that should allow the original defaults in vanilla to still populate for that faction without the dialogue options. That is very much an educated guess though, and will be done in an "upon request" kind of way.
Similarly, if you have implemented custom dialogue for your mod faction, and would like these options to be included in the interim between release and if/when I can set up some way of doing this in the mod faction's directory, you can post here and I will implement the dialogue with the necessary script in this mod.
*EDIT* Added above info to main mod page.
