Written down, most of it seems within the expected range for 2.5-3. Some things are a little quirky and I'd be inclined to keep an eye to see how things develop. Things like the scripting or the answering with strings of random words. It might die away in the next few months as her language comes on, no big deal, just how she acquired language. Or it might persist, and might raise further questions.
Similarly with pretend play – usually you'd see some by now (not anything massively complex, putting baby/teddy to bed, cooking in the play kitchen, making dinosaurs stomp and roar). But maybe she just doesn't do very much of it, and you haven't happened to see it. What if you start a teddy bear's tea party, will she join in?
Is she completely uninterested in other children? Lots of children this age play alongside, so semi-socially playing with similar stuff next to a child, but not really with them, beyond something like a game of chase. What about with an older child who might support/direct the shared play a bit? Would she engage with them?
Does the tantrum usually stop fairly quickly if she gets her way? If tantrumming gets her something she wants, she will naturally do it more. More concerning would be if the tantrums aren't actually tantrums, but meltdowns, where she's so overwhelmed/disraught that she can't stop, no matter what you offer her (but even a few of those are normal for toddlers, especially if hungry or tired).
The other thing is that humans are complex creatures, even as toddlers, so it's hard to capture fully behaviour in words. If in person, things feel 'different', that could well be – it's very hard to tease out what's standard quirky toddler and what's something more.
