Both explanations would be good. It seems like any class I look at, including cavalier, it says to treat your level as druid level, but the list of companions available to a druid doesn't have the t-rex on it, so I'm lost as to how people are getting it this way. But honestly, I think I'd rather get access to one without being glued to a class if possible

The largest a companion can get, besides with the increase from the Mammoth Lord, is a large. And they do increase in strength through the animal companion class feature, like better natural armor, more feats, tricks, skill points, etc. Sure a creature size is stunted from the animal companion rules, but they get more than enough extra things from the class to compensate.

As to your question, I have to ask what you mean by mount. Do you mean something that you ride on, or the actual mount class feature for a cavalier or paladin?
If you want the mount mount, the Beast rider cavalier archetype will let you do that.
If you want to ride it, the beastmaster ranger, or any druid can select one as an animal companion and hop on it.
It does get stronger after level 7. Animal companions can be a little tricky. MOST of how they grow is on the chart in the druid section. THey gain more HD, base attack bonus, strength, dex, natural armor, special abilities and feats based on that. At 7th level they ALSO have a big jump in power, gaining size and strength.

If all you have is gold and the DM is feeling nice, the animal archive has rules for buying a combat trained one strait out of the bestiary.

I could buy one stock I suppose, but gargantuan is super unwieldy, plus you couldn't afford it at early levels. I guess I'm wondering if there's a way to get one right away and then advance it to huge and give it swallow whole later on.
If that's not possible then my next question would be, can I buy a huge one with swallow whole, and if so, how much would it cost.

Thanx Chess. The address didn't work but I was able to navigate my way there by looking at it. Here is a working link if anyone else should ever read this and be interested.
How would I go about getting it as a huge creature though? Reduce animal would make it huge but its not on the list of spells that qualify for permanency.

Find a baby T-rex. One with the young template.

you nailed it sir, this will work perfect. Tyvm
