Randomized Structure Loot
Adding loot tables to containers in structure is easy, you need to have a PC and your choice of either NBT Studio (executable) or Loot Tabler (browser application).
Setup
Creating the Loot Table
To start, create the directory BP/loot_tables/chests and create your loot table file here.
You can learn how to make loot tables in Beginner's Guide

}Exporting Structure
Once you have created your loot table, export your structure into BP/structures. Then follow the steps for either NBT Studio or Loot Tabler
NBT Studio (Executable)
Software Preparation
Download and launch NBT Studio
Adding the Loot Table
Launch NBT Studio and open file (Ctrl + O)
Find your container (Ctrl + F)
Navigate to your container, block_position_data > block_entity_data. Add a string tag
Add LootTable and the file path to your loot table
Save changes (Ctrl + S)
Loot Tabler (Browser Application)
TIP
To export a structure on mobile devices, Download this pack.
Adding the Loot Table
Open the website and click "Upload". Choose your structure file.
Find your container in the containers list, making use of the information displayed under "Container Options"
Under "Loot Table", enter the path to your loot table. Set "Loot Table Seed" to blank or 0 if you want the loot to generate randomly. If you want the loot table to generate consistently, enter a specific value.
Download your structure file and place it in BP/structures.
Jigsaw Processors
Processors for jigsaw structures can set blocks like suspicious sand and chests to have loot.
This can be done using a minecraft:rule processor with a block_entity_modifier rule. The type field should be specified to minecraft:append_loot with the loot_table being set to the path to your loot table.
Using that rule in combination with blockstate_match predicates will allow for blocks to be given loot tables.
A processor setting a chest to have loot will set it to the default rotation unless blockstate_match is set to match the input chest with the loot table and then output a chest with the loot table and same rotation. A rule is needed for all permutations of the block you want to replace. For example, chests have 4 cardinal directions so 4 rules would be needed.
All of the specified blocks in the structure template with the processor applied will have the loot. There is no way to have different loot in different chests in the same structure template using processors.
Example

]Testing
Load your structure and open the container. For jigsaws use /place structure or /place jigsaw.
