If chipped properly, it won't produce much sap so ants shouldn't be a problem. And go ahead and use it around any woody plants - it won't increase soil acidity to any significant degree. If incorporating the chips into the soil to fill a low area, you may want to add a nitrogen source to offset the depletion wood chips mixed with soil will create. But if you are just using a mulch or topdressing, no worries!

That sounds like delicious mulch. I've been harvesting damaged bags of chipped pine wood sold in compressed bales as horse bedding, from the dumpster at the farm supply. If a bag gets ripped then it rains and gets it wet, they just toss it. I have like 10 3 cu ft bales. Thinking about using them for path mulch in the garden, but also wondering if it would compost given enough greens.

Wood Chips will compost, quite well, and can make a fairly decent soil. Many places that have been mulched with wood chips are now growing good, healthy plants because the Soil food Web has digested that wood chip mulch into something that will support plant growth. You will need to balance the chips with a Nitrogne source (greens) in the compost bin.

Yes!

My housemate's mom used all the pine trees we shredded and chipped on her garden and it was way better than usual.

I wonder how big the chips will be. If it is coarse chipped, it will take some time to break down.

You might try composting them for a month or so. Pile them into a pile and cover it with a plastic cover to slow the moisture loss. It will heat up for a time. When it cools off, go ahead and use it like a mulch. The partial decomposition will help it act as a weed suppressant.

Idaho, there is no good reason to do that. When I have had the wood cutters deliver a 5 yard load of wood chips that pile would tend to get quite warm, but when I dug out thoe chips and spread them where they were to go they cold down and suppressed any weeds really well until the Soil Food Web digested them enough that they made a good growing medium. The size of the wood chips makes little difference.

The partial decomposition will help it act as a weed suppressant.

That's an interesting statement but I wonder about its validity. Why would partial decomposition increase the ability of wood chips to suppress weeds? Can you explain further?
