The number of inodes is decided at mkfs time and can't be changed easily. If your OSTs are on lvm, one option could be to increase the size of the logical volumes and resize the backend ldiskfs filesystems. However, i'm not sure someone has ever tried this with ldiskfs/lustre, so i would not do this on a production filesystem w/o some testing first. In any case, i think the issue here is that you seem to have a default stripe count of -1. That's why you are limited by the number of inodes available on one single OST. You should still be able to create ~1.250M x 18 = 22.5M 1-stripe files.
