I wouldn’t worry too much about it - outdoor plants are much more resilient - especially if you have it in the ground.
I’ve had ones do similar sideways growth and they usually straighten out somewhat.
But again, there’s such a massive root base and strength in that trunk from wind blowing it around and that natural sun light.. I wouldn’t sweat it unless it continues to grow towards being parallel with the ground past 45. Outdoor plants are strong as heck!
