What a pity about the forks
The rest of the bike looks to be in good shape under the grime.
Me, I'd be tempted to try to straighten them. Nothing to lose by trying so long as it isn't expensive.
Replacement forks, if you can find them, will need painting and not a prospect IMHO.
Looks to be steerer as well as lower down, but I've straightened worse before with judicious use of hydraulic car/auto chassis equipment.
The safety aspect isn't really much of an issue since it is not the type of bike that is going to be overstressed.
Steel is very forgiving, with a good bit of elasticity, and a few degrees either way is not going to be too traumatic to reverse. It's done on cars all the time.
