Update: They won, but every single party has said they will not work together with Herbert Kickl. Maybe with the FPÖ without him though (they didn’t specifically rule that out), but I doubt the FPÖ will be willing to drop him after getting their best result in history so far (nearly 29%).

The only possible coalitions without it would be ÖVP (people’s party) + SPÖ (social democratic party) + NEOS (center (economic right (less regulation) else left)) or ÖVP + SPÖ + Green Party.

Technically ÖVP + SPÖ would also work by a very slim margin (out of 92 needed mandates to form a coalition (183 mandates in total) they’re getting 92 or 93) but wouldn’t hold much power (failing to get a majority if one single mandate doesn’t agree to something) which is why it’s more likely that they also include NEOS or the green party.
