I am a newbie to growing things from seed and need some help with some mammoth sunflowers.

I started these guys indoors and they've been outside for a few weeks but many have a very similar bend. Are these guys in big trouble? I would imagine they won't be able to support themselves like this and wondering if they can be staked straight? A few others have the same bend but thick red stems below the first set of leaves.

Any help would be appreciated!

I wonder if the issue with your Sunflower (Helianthus annuus 'Mammoth') is possibly due to inadequate light?

They were much smaller with the bend when I moved them outside where they get full sun for most of the day. I thought it might correct on its own, but they haven't. The shadow in this picture is me taking the picture.

The pots are so small that they are stunted. You say they've been outside for "a few weeks". If they had been in the ground or a WAY bigger pot for that time they'd be a few feet high with thick stalks by now. At this point it is unlikely that they will ever be upright and they won't grow to their full size, but if you increase their growing space and stake them, you'll likely get flowers.

Mammoth sunflowers grow to 10+ feet in the right environment. Visualize the size that the roots need to be to support that height. A lot of people make this mistake. It might not be too late to start new seeds Crossing Fingers!
For me, gardening is really just an excuse for playing in the dirt. Admittedly, plants are a satisfying by-product.

Thanks -- I think I was too worried about leaving the "on their own" in the ground. I put some in the ground earlier and they ended up trampled or nibbled on.
