Hi Josh, so probably the best way to get that area filleted is to repair the object so that it is smooth along that whole cutout rather than just slightly sharp at that closing area as shown above.
The way I did that was to use "untrim" to recover the larger cutting surface and to remove the holes in the main object, there is some info on how to do that in this post about untrim here:

And there's more detailed information on this kind of low level surface repair process in the object repair tutorial here:

Once I had the original cutting surface extracted, I used Edit > Trim with the "isoparm" option to slice up the surface making some empty space between its ends and then putting in a blend surface between the edges so that it will be a smooth closed shape like this:
Then after repairing a couple of unjoined edges in some other areas of the shape I used boolean difference to cut those now smooth cutting surfaces out from the main object, and now the resulting structure with all smoothly meeting pieces in those areas should fillet ok.
I've attached the repaired 3DM file which you should now be able to fillet, the edges to fillet are now made up of 2 edges instead of just one so make sure to select them as well when you go to do the fillet:
Hope this helps! You want to try and void making slightly sharply meeting pieces like that if you want to fillet them later on, slightly sharp meeting things tend to be particularly difficult to fillet.
