I've been trying to add loot tables to my blocks + override vanilla ones but it posts this warning message despite what I do, and it's becoming annoying.
The loot tables work, but I want to get rid of this warning message so I can actually do this right.
What does this mean?

Example loot table json (most of them are like this):

{
    "type": "minecraft:block",
    "pools": [
        {
            "name": "organic_grass",
            "rolls": 1,
            "entries": [
                {
                    "type": "minecraft:alternatives",
                    "children": [
                        {
                            "type": "minecraft:item",
                            "conditions": [
                                {
                                    "condition": "minecraft:match_tool",
                                    "predicate": {
                                        "enchantments": [
                                            {

                                        ]
                                    }
                                }
                            ],

                                },
                                {

                                }
                            ],

                        },

        }
    ]
}

Your pool is of type "alternatives", which means "select one sub-entry from a list".  Your second sub-entry (dirt_chunk) has no condition, so it's always successful; therefore the third entry (grass_seeds) will never be reached.

Any condition you want.

What's your goal?

I want for it to always give dirt chunks when broken, but only grass seeds within a chance.

As I understand it you'd have to use multiple entries then.

like this?

{
    "type": "minecraft:block",
    "pools": [
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "minecraft:item",
                    "functions": [
                        {
                            "function": "minecraft:set_count",
                            "count": 4
                        },
                        {
                            "function": "minecraft:explosion_decay"
                        }
                    ],
                    "name": "undergroundadditions:dirt_chunk"
                },
                {
                    "type": "minecraft:item",
                    "conditions": [
                        {
                            "condition": "minecraft:random_chance",
                            "chance": 0.125
                        }
                    ],
                    "name": "undergroundadditions:grass_seeds"
                }
            ]
        }
    ]
}

Looks right. But I am not 100% sure how multiple entries behave - i.e. if they always all generate.

What do you mean? Also, it works.

diesieben07's comment was in reference to the fact that by just looking at the json he can't be sure that it's correct. It looks right, but not completely sure. The only way to find out is to run the game and test it.
